Question

For a particular reaction, heat of combustion at constant pressure $\left(q_P\right)$ is always greater than that at constant volume $\left(q_V\right)$.
If true........1
else ...........0

• A. 0

Answer 1

The correct option is A 0
As we know,
$\Delta H=\Delta U+\Delta nRT$
so if $\Delta n=0$
then, $\Delta H=\Delta U$
$q_P=q_V$
