Question

A ________________△H corresponds o an ___________ process.

A) negative, endothermic
B) negative, exothermic
C) positive, exothermic
D) zero, exothermic

Answer 1

A negative △H corresponds to an exothermic process.

⇒ B) negative, exothermic

What is Enthalpy?

∆H is the change in enthalpy within a system. Enthalpy is the sum of the internal energy within that system.

Equation

H = E + PV = Change in internal energy + Pressure * Volume

Step-by-step explanation

In endothermic processes, the amount of energy within the system increases and therefore ∆H increases. In exothermic processes, the amount of energy within the system decreases and therefore ∆H decreases. The best way to remember this is exo is energy exiting the system.
