Hi, so to answer this question, we have to remember le chatelier's principle.
00:07
When a reaction at equilibrium is stressed, so that means if there's a change in pressure, temperature, or concentration of products or reactants, then the equilibrium will shift in the opposite direction to offset the stress or the change in the reaction.
00:26
So if we have here an endothermic equilibrium equation, so example we have this reaction, reactant a producing, let's say, 2b.
00:40
And then since this is endothermic reaction, so that means delta h of this reaction will be positive.

Let's say we have positive 10 kj per mole, okay? let me just write here, this is an example...
