For the reaction, 2A(g)+B(g)to2D(g) ...

For the reaction,
`2A(g)+B(g)to2D(g)`
`DeltaU^(theta)=-10.5 kJ and DeltaS^(theta)=-44.1 JK^(-1)`
Calculate `DeltaG^(theta)` for the reaction, and predict whether the reaction can occur spontaneously or not.

Text Solution

Verified by Experts

`DeltaH=DeltaU+Deltan_(g)RT`
`DeltaH=-10.5+(-1)xx8.314xx10^(-3)xx298`
`=-12.97 kJ`
`DeltaG=DeltaH-TDeltaS`
`=-12.97-298(-44.1xx10^(-3))=0.164 kJ`
