According to Le Chatelier's principle, increasing the temperature will shift the equilibrium in the direction that absorbs heat, which in this case is the endothermic decomposition of Ni(CO)₄ into Ni and CO. As a result, an increase in temperature favors the decomposition of Ni(CO)₄ into Ni and CO, leading to an increase in the yield of Ni and CO. Therefore, choice C is the best option. The other choices involve an increase in pressure, which has no effect on the direction of the reaction as both the reactants and products are in the gaseous phase.
