A chemical plant produces ammonia using the following reaction at high temperature and high pressure. Which issue are plant engineers and investors most likely to see as a drawback of this method? 3H2 + N2 = 2NH3 + energy A. This reaction system will solidify at a higher temperature and obstruct the equipment O B. The high pressure will increase the rate of the reactant-favored reaction at equilibrium. O C. The high temperature will increase the rate of the reactant-favored reaction at equilibrium. D. Maintaining a high temperature will require burning fossil fuels or using a great deal of electricity.
