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

At 300 K, the enthalpy change and entropy change of a reaction are -10 kcal and -30 " cal". K^(-1) respectively. Does the reaction occur spontaneously at 400 K ? If not, then calculate the maximum temperature at which the reaction will occur spontaneously ?

The entropy change for eaction at 300 K is 120 Jk^(-1) mol^(-1) . What is the enthalpy change for the reaction ?

Preidict which of the following reactions would not procees spontaneously at 298 K

Predict which of the following reactions would proceed spontaneously at 298K?

Predict which of the following reactions would proceed spontaneously at 298K?

The standard free energy change for a reaction is -212.3 kJ mol_-1 . If the enthalpy of the reaction is 216.7 kJ mol_-1 , calculate the change in entropy in the reaction at 298K.

The entropy chnge for a non-spontaneous reaction is 140 J/K.mole at 298 K. The reaction is_____________.

Gibbs-Helmoholtz equation relates the free energy change to the enthalpy and entropy changes of the process as (DeltaG)_(PT) = DeltaH - T DeltaS The magnitude of DeltaH does not change much with the change in temperature but the enrgy factor T DeltaS changes appreciably. Thus, spontaneity of a process depends very much on temperature. The enthalpy change for a certain reaction at 300K is -15.0 kcal mol^(-1) . The entropy change under these conditions is -7.2 cal K^(-) mol^(-1) . The free enegry change for the reaction and its spontaneous//nonspontaneous character will be
