Best ResponseYou've already chosen the best response.0I don't know, c? I guessed B, but it wasn't correct. I don't understand any of it.

Best ResponseYou've already chosen the best response.2So the rxn is exothermic. So heat is a product

Best ResponseYou've already chosen the best response.2You're adding more heat so think of it this way the reaction is exothermic so when you add heat in there's too much heat so the reaction will go to the left and decrease the amount of product.

Best ResponseYou've already chosen the best response.0I'm still not understanding what the answer would be then, or how to figure it out.

Best ResponseYou've already chosen the best response.1It's like this: We are given with the enthalpy right? It's a positive charged number which means this is an exothermic reaction. Because in exothermic reactions the heat is given out so enthalpy change is positive. Can u understand this part?

Best ResponseYou've already chosen the best response.1When we increase the temperature the equilibrium becomes unstable right ?

Best ResponseYou've already chosen the best response.0Yes. Would it be D, then? Or am I jumping too far ahead? Lol.

Best ResponseYou've already chosen the best response.1I thought it would be A though ! What do u think @Photon336 and @taramgrant0543664

Best ResponseYou've already chosen the best response.0According to Le Chatelier's principle the reaction always tries to minimize the stress developed by external conditions. In this case if we increase the temperature the reaction will try to do something which will decrease the temperature. Since the forward reaction is exothermic, equilibrium will shift toward backwards and hence more products will disintegrate to form reactants thus amount of ethane will decrease.
