Spontaneous Reaction |Entropy And Spontaneity |Questions |OMR|Summary

Explain entropy and spontaneity of the process.

Assertion : If both DeltaH^(@) and DeltaS^(@) are positive then reaction will be spontaneous at high temperature. Reason : All processes with positive entropy chang are spontaneous.

Based on entropy change predict a spontaneous reaction among the following. A:(NH_(4))_(2)CO_(3(s))rarr2NH_(3_((g)))+CO_(2_((g)))+H_(2)O_((l)) and B:NH_(3_((g)))+H_(2)S_((g))rarrNH_(4)HS_((s))

Entropy Change for System and surrounding

The entropy change in the conversion of water to ice at 274 K for the system is -22.13 JK^(-1)mol^(-1) and for surrounding is +22.05 JK^(-1)mol^(-1) . State whether the process is spontaneous or non-spontaneous.
