The enthalpy change (`DeltaH`) of the reaction at 298 K
`C_2H_5OH(l) + 3O_2(g) to 2CO_2(g) + 3H_2O (l)`
is found to be -326.7 kcal. Calculate `DeltaE` for the given reaction.

AI Generated Solution

To calculate the change in internal energy (ΔE) for the given reaction, we can use the relationship between enthalpy change (ΔH) and internal energy change (ΔU). The formula is: \[ \Delta H = \Delta U + P \Delta V \] From the ideal gas law, we can relate the change in volume (ΔV) to the change in the number of moles of gas (Δn): ...
