If the reaction producing nickel is as follows: Ni(CO)4(g) + heat Ni(s) + 4CO(g) - Heat The reaction from left to right is endothermic and, therefore, the addition of heat will accelerate the production of nickel.
According to Le
Chatelier's Principle the position of equilibrium moves to counteract the
change. Because heat is reactant, adding more heat shift reaction to he right, so system consume that heat.
