Enthalpy and enthalpy change

Question

For exothermic and endothermic reaction, the sign of $q_{p}$ respectively are

Easy

A

positive, negative
B

positive, positive
C

negative, negative
D

negative, positive

Solution

In an exothermic reaction, heat is evolved and system loses heat to the surroundings. Therefore, $q_{p}$ will be negative and $∆_{r}$ , H will also be negative. In an endothermic reaction, heat is absorbed, $q_{p}$ is positive and $∆_{r}$ H will be positive.
