The entropy change for eaction at 300 ...

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

Text Solution

Verified by Experts

The correct Answer is:
`Delta H^(@) = 36 kJ mol^(-1)`
`Delta S^(@) = (Delta H^(@))/(T)`
`:. Delta H^(@) = T Delta S^(@)`
`= 300 xx 120`
`= 3.6 xx 10^(4) Jmol^(-1)`
` =36 kJ mol^(-1)`

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
