The author explicitly states that both women were fighting to kill, despite Molly refraining from casting the Unforgivable curse Avada Kedavra. The result of the duel actually comes about as a result of nothing more than spectacular accuracy on Weasley's part.
In the final movie, Harry Potter and the Deathly Hallows pt. 2, Molly first hits Bella with a spell that freezes her, most likely Petrificus Totalus. Then, she launches another one that shatters her entire body into pieces, which could be expelliarmus, bombarda, stupefy, or any spell that can produce such an effect.
Molly's curse soared beneath Bellatrix's outstretched arm and hit her squarely in the chest, directly over her heart. The Killing Curse is the only spell we know of which does noting except kill, but there are many spells which *can* kill.
Why doesn t Harry use Avada Kedavra on Bellatrix? Harry didn't use that spell because he cannot bring himself to kill anyone. He is not a killer.
His reaction to Bella's death was akin to his reaction at the loss of the Cup, which was when he realised that his own immortality was jeopardised amidst war and his own death could have been near.
In Deathly Hallows, Hermione faced a real test of her physical and psychological stamina. After being on the run from a bunch of Snatchers, the gang were taken to Malfoy Manor, where Bellatrix proceeded to torture Hermione using the Cruciatus Curse.

With all of those symptoms being met, it wouldn't be unreasonable to consider her as having a borderline personality disorder. Bellatrix Lestrange “was obsessively in love with Lord Voldemort, which extended to her being… attracted to him” (wiki).
Molly Weasley isn't stronger than Bellatrix.
The result of the duel actually comes about as a result of nothing more than spectacular accuracy on Weasley's part. She casts a powerful, unnamed curse at Lestrange and manages to hit her directly in the heart, killing her instantly.

Ron never cast any kind of curse on Nagini, not in the book anyways. And there's no confirmation that the spell he used on her in the movies was the Killing Curse. Avada Kedavra isn't the only spell that creates green light, after all.
Ginny and the Bat Bogey Hex
As the youngest Weasley, we're sure Ginny observed more than her fair share of unpleasant spells over the years but it was the Bat Bogey Hex she was famous for – and with good reason.
The only clear canon instance of a good wizard using Avada Kedavra to kill is Snape's euthanasia of Dumbledore.
Bellatrix had a fear of rejection as well where Voldemort was concerned, wanting nothing more than to please him but was always frightened that she would lose his favor.
Draco had several reasons for lying to Bellatrix, including the fact that he was never a bad person. Moreover, he no longer found working for the Dark Lord appealing and hated how Voldemort treated his family. He did not intend to harm anyone and believed Harry was the only person capable of defeating Voldemort.
Voldemort is a master manipulator. By humiliating Bellatrix as he does, he punishes her for her part in the failure at the Ministry of Magic — including her failure to finish off Tonks — and rouses her to try harder to murder members of her family.
If Bellatrix managed to muster affection for anyone other than Voldemort, it was her younger sister (even at the height of the Second Wizarding War, Bellatrix and Narcissa called each other Cissy and Bella, no doubt childhood nicknames they'd given each other).
Bellatrix Lestrange Killed her own cousin, Sirius Black: She killed Sirius (who was her cousin) during the battle at the Department of Mysteries. She was remorseless and was cackling in glee after she had murdered Sirius.
Roughly translated, Expelliarmus – the Disarming Charm – means 'to drive out a weapon' and that's what it does: forces the subject to drop whatever they're holding. Usually that's a wand, which is why it's often seen in duels, and Harry definitely took that to heart, given how much he used it in combat.
The darkest of the Dark Arts, Harry Potter unforgivable curses are the Cruciatus Curse, the Imperius Curse, and the Killing Curse. Although the curses are highly illegal, Harry using Unforgivable Curses happened, but he uses them once he was thrust into the Second Wizarding War.
According to The Leaky Cauldron, when a fan asked if Hermione made sure that her parents could remember her again, Rowling said, "she brought them home straight away." This is good news, as it's awful to imagine Hermione's parents never remembering who she is or ever seeing her again.
Because to a pureblood fanatic like Bellatrix, Harry is a Mudblood because one of his parents (Lily Evans) was a Muggleborn. Anyone with Muggle ancestry is one, including Snape since his father was a Muggle (Tobias).
