Video transcript

Hello everyone. So in this video we're taking a look at this equation right here. Of course this is an equilibrium equation. Given the equilibrium arrows were given in the problem that this is an endo thermic reaction. Whenever we have an endo thermic reaction, heat is going to be a starting material or a reactant. In that case let's go ahead and actually rewrite the equation then. So we have everything staying the same except adding the heat on the left side now. Alright, so because of this then whenever we're increasing temperature, we're adding heat when we're heading heat, which is going to be a starting material, then the equilibrium will shift towards the right. So the crowd answer to our problem is going to be a So the reaction will shift to the right when the temperature is increased and it will shift to the left when it is decreased. On the other hand, the equilibrium constant decreases as the temperature of the reaction is increased. But that's going to be my final answer for this problem. Hopefully this helps
