Answer:
A) True/True
Explanation:
Non spontaneous exothermic reactions <u>need to reach the activation energy to get started</u> (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, <u>exothermic reaction's conversion of equilibrium is decreased when heat is addeed to the system. </u>
