The forward reaction in the Haber process is exothermic. What is the effect of increasing the temperature on the yield of ammonia at equilibrium, and why?
The yield increases, because the forward reaction is exothermic
The yield decreases, because the forward reaction is exothermic
The yield increases, because the forward reaction is endothermic
The yield decreases, because the reverse reaction is exothermic
