Text Solution

AI Generated Solution

To calculate the heat of combustion of benzene at constant pressure, we can follow these steps: ### Step 1: Understand the relationship between ΔH and ΔU The heat of combustion at constant pressure (ΔH) is related to the heat of combustion at constant volume (ΔU) by the equation: \[ \Delta H = \Delta U + \Delta N_g RT \] where: ...
