Question

what is the effect of increase in temperature for the reaction 2no2(g) = n2o4(g) ∆h= -572kj

Answer 1

If you increase the temperature, the position of equilibrium will move in such a way as to reduce the temperature again. It will do that by favouring the reaction which absorbs heat. In the equilibrium we've just looked at, that will be the back reaction because the forward reaction is exothermic.

Answer 2

Explanation:

if u apply heat to an exothermic reaction, exothermic forward reaction will decrease increasing the exothermic backward reaction.
