Question

Which of the following statement is correct.

• A. $- 11.7 \times 10^{3}Jmol^{- 1}$ is positive for exothermic reaction
• B. $- 105Jmol^{- 1}K^{- 1}$ is negative for endothermic reaction
• C. The heat of neutralization of strong acid and strong base is always the same.
• D. The enthalpy of fusion is negative

Answer 1

Answer: (C)

The heat of neutralization of strong acid and strong base is always the same.

Answer 2

$9.92 \times 10^{8}Pa$ for exothermic reaction.

$9.92 \times 10^{7}Pa$ for endothermic reaction

Enthalpy of fusion is + ve.
