The heat of combustion of solid benzoic acid at constant volume is `-321.30 kJ` at `27^(@)C`. The heat of combustion at constant pressure is

Options

A. `-321.30-300R`
B. `-321.30 +300R`
C. `-321.30-150R`
D. `-321.30-900R`

Explanation

To find the heat of combustion of solid benzoic acid at constant pressure (ΔH) when the heat of combustion at constant volume (ΔU) is given, we can use the relationship between ΔH and ΔU. The equation we will use is:

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

Where:
- ΔH = change in enthalpy (heat of combustion at constant pressure)
