Answer 1

Answer #1

The reaction is

The change in Gibbs Free energy is given by the equation -

Here , K_p is equilibrium constant under constant pressure

R is universal gas constant = 8.314 Jmol^-1K^-1

T is temperature = (25+273) K =298 K

The equilibrium constant of the mentioned equation is

Thus ,
