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, we can use the relationship between the heat at constant volume (ΔU) and the heat at constant pressure (ΔH). The equation we will use is:

\[ \Delta H = \Delta U + \Delta nRT \]

Where:
- \(\Delta H\) = heat of combustion at constant pressure
