The enthalpy change `DeltaH` for the neutralisation fo `1M HCI` by caustic potash in dilute solution at `298 K` is

The standard enthalpy change for the neutralisation of HCN with NaOH is -2460 cal at 298 K. Given that standard enthalpy change for the neutralisation HCl with NaOH is -13.7 kcal. What is enthalpy of ionisation of HCN in kcal ?

The enthalpy change (DeltaH) for the reaction N_2(g) + 3H_2 (g) to 2NH_3(g) is -92.38 kJ at 298 K. What is DeltaU at 298 K ? (R = 8.314 j K^(-1) mol^(-1))

The enthalpy change for a given reaction at 298 K is -x cal mol^(-1) . If the reaction occurs spontaneously at 298 K , the entropy change at that temperature
