The difference between the heats of reaction at constant pressure and a constant volume for the reaction `2C_(6)H_(6)(l) + 15O_(2)(g) rarr 12CO_(2)(g) + 6H_(2)O(l)` at `25^(@)C` in `kJ` is

Options

A. `-7.43`
B. `+3.72`
C. `-3.72`
D. `+7.43`

Explanation

To find the difference between the heats of reaction at constant pressure (ΔH) and constant volume (ΔU) for the given reaction, we can use the relationship:

\[ \Delta H = \Delta U + \Delta N_g RT \]

where:
- ΔH is the change in enthalpy at constant pressure,
