Q. 16

In an exothermic reaction, heat is evolved, and the system loses heat to the surrounding. For such a system
A. qp will be negative

B. ΔrH will be negative

C. qp will be positive

D. ΔrH will be positive

Answer :

Reason: In an exothermic reaction heat is released which is indicated by the negative sign of ΔrH.

And we know the relation that ΔH=qp, at constant pressure.


So, if ΔH is negative which means thatqpwill also be negative.
