Work Step by Step

1. Count the amount of product molecules at $T_1$ and $T_2$: $T_1$ : 2 molecules $T_2$: 8 molecules - The equilibrium shifted in the direction of the products when the temperature increased (from 100 $^oC$ to 200 $^oC$). Therefore, the heat is on the reactants side, so the reaction is endothermic.
