Question

The delta G for above reaction A↔B is 24.5KJ/mole under standard conditions. at equilibrium a student adds and addition 4 moles of A and 2 moles of B this addition makes the reaction go which direction?

Answer 1

Hi Arsineh! I'd be happy to help you with your question. :)

Since the delta G is positive, this means that the reaction is non-spontaneous, and would need energy input (such as heat) for it to proceed forward from A to B. However, when the reaction is at equilibrium, delta G equals 0. Thus, following Le Chatelier's Principle, we can see that adding more reactant A than product B would shift the reaction to the right, towards the product.

Hope this helps,
