The following equation represents the decomposition of a generic diatomic element in its standard state.  

1/2x^2 (g) yields X(g)

assume that the standard molar Gibbs energy of formation of X(g) is 4.45 KJ *mol^-1 at 2000. K and -51.20 KJ *mol^-1 at 3000. K. Determine the value of K (the thermodynamics equilibrium constant) at each temperature.  

At 2000. K, we were given: delta Gf =4.45 kj*mol^-1. what is K at the temperature?

K at 2000. K = ?

At 3000. K, we are given: delta Gf =-51.20 KJ* mol^-1. what is the K at that temperature?

K at 3000. K= ?
