Law of mass action

A few questions.

For irreversible reactions, would K just be the concentration of products? Or infinity?

Also, does le chatelier's principle apply to irreversible reactions?

Does heat effect irreversible reactions? The Q or K values? Well, I think adding heat or increasing temp? effect only K and not Q right? Man, I think I am screwing my gchem scores by over thinking stuff. Lol

For irreversible reactions, would K just be the concentration of products? Or infinity? not too sure about this sorry

Also, does le chatelier's principle apply to irreversible reactions? NO

Does heat effect irreversible reactions? yes heat can still affect irreversible reactions

Thanks MC Grammar! 😉

How does heat affect an irreversible reactions then? Like if heat was added to an exothermic or endothermic reaction.

For irreversible reaction, there is no equilibrium and all reactants go to completion. Heating it will speed up the reaction for an irreversible reaction. For a reversible reaction, you will have to use Le Chatelier's principle and figure which direction it will drive the reaction towards with heat. So change in Temp only affects K(eq) not Q.

Irreversible concentration is whatever the starting concentration was. If you have 1 M of NaOH, you would get 1 M of Na+ and 1 M of OH-.
