Equilibrium Constant

A reaction is found to have an equilibrium constant of 600 at a temperature of 300K and a pressure of 1.0 atm. It can be concluded that at these conditions:

I. ΔH < 0 II. ΔS < 0 III. ΔG < 0

C.

Since K > 0, the reaction is spontaneous, and ΔG < 0; ΔG = -RTln(k) Although ΔH and ΔS combine to determine ΔG, we lack information to determine the sign of either of them. [/hide-this-part]
