Question

The free energy profile as the reaction goes from reactants to products is a straight diagonal line from 50 kj/mol to 80 kj/mol. Is the reaction exothermic or endothermic? Does the reaction involve only pure solids and liquids? Is the equilibrium constant greater than, equal to or less than one? Is the change in the number of moles of gas equal to zero? At equilibrium, will products be formed?
