Question 35 (1 point) The relationship between the activation energy of the forward and reverse reactions is related by the energy difference between the reactants and products. If the reactants are higher in energy than the products, the activation energy for the forward reaction will be smaller than the activation energy for the reverse reaction and vice versa True False Question 36 (1 point) A catalyst is a substance that is not used up during a reaction. It also does...

Determine whether each of the following statements about the thermodynamic functions are True or False as they apply to chemical reactions. True False Spontaneity is increased by positive entropy changes. True False All spontaneous chemical reactions have negative heats of reaction. True False Spontaneity is increased by negative enthalpy changes. True False Entropy and enthalpy are multiplied in the Gibbs free energy. True False The heat of reaction at constant pressure is always equal to the work done by the reaction.
