Estimate delta Grxn for the following reaction at 427K.

HCN(g)+2H2------->CH3NH2(g)

delta H= -158.0Kj

delta S= -219.9 j/k

+64.1kJ

-64.1kJ

-252kJ

+61.9KJ

+252Kj

Solutions

Expert Solution

answer : -64.1kJ

delta H= -158.0Kj

delta S= -219.9 j/k

delta G = delta H - T x delta S

             = - 158 - 427 x - 0.2199

             = - 64.1 kJ/mol

delta Grxn = - 64.1 kJ/mol
