H2(g) ZnO(s) = H2O(g) Zn(s)

Question

(f) Calculate the value of ∆Go for the reaction.

(g) Is the reaction predicted to be spontaneous under standard conditions at 25 degrees Celsius?

(h) Is the equilibrium constant for the reaction greater than 1 or less than 1?

Answer 1

....H2(g)  &   ZnO(s) =>   H2O(g)   &   Zn(s)

dGf: O   &  -318.2 -->  -->  -228.57   &   0

dG = prod - reactants

dG = -228.57 - (-318.2)

your answer is dG = + 89.6 kJ

==================================

because dG = "+" ..

your answer it is not spontaneous

==========================

because the products are not favored,

yuor answer is: the K is less than 1
