What is the enthalpy of the reaction from 15^oC to 25^oC if CP = 3 J/^oC, and the reference enthalpy is 15 J?

(a) 15 J

(b) 30 J

(c) 45 J

(d) 60 J

I had been asked this question in homework.

The correct option is (c) 45 J

The explanation is: Enthalpy of reaction = 15 + 15∫^253.dT = 15 + 3*10 = 45 J.
