A synthesis reaction that is nonspontaneous and has a negative value for its heat of reaction will not occur until some heat is added

nonspontaneous exothermic re actions need enough activation energy to get them started.

A. T, T

B. T, F

C. F, T

D. F, F

E. T, T, CE

A) True/True

Explanation:

Non spontaneous exothermic reactions need to reach the activation energy to get started (like all non spontaneous reactions), usually this energy is given in the form of heat. So you can say the second statement is True

The first one is also True, if you don't give some energy (heat) to a non spontaneous reaction it won't start. Never the less, exothermic reaction's conversion of equilibrium is decreased when heat is addeed to the system.
