The enthalpy of combustion of benzoic ac...

The enthalpy of combustion of benzoic acid `(C_(6)H_(5)COOH)` at `298K` and `1atm` pressure is `-2500.0 kJ mol^(-1)`. What is `DeltaU` for the reaction?

Text Solution

AI Generated Solution

To find the change in internal energy (\( \Delta U \)) for the combustion of benzoic acid, we can use the relationship between enthalpy change (\( \Delta H \)) and internal energy change (\( \Delta U \)) given by the equation: \[ \Delta H = \Delta U + \Delta N_g R T \] where: - \( \Delta H \) is the enthalpy change, ...
