Based on the value of ∆Go and the chemical reaction, which of the following is true about the reaction?

Question

2 EMZ₃(g) ⇌ 2 EZ₃(g) + M₂(g)

∆G^o_rxn = −350 kJ/mol_rxn

A small sample of EMZ₃ is placed into an evacuated, rigid metal container and allowed to reach equilibrium. Based on the value of ∆G^o and the chemical reaction, which of the following is true about the reaction?

1. The value of K is much less than 1 and more products form than reactants
2. The value of K is much less than 1 and more reactants from than products
3. The value of K is much greater than 1 and more reactants from than products.
4. The value of K is much greater than 1 and more products form than reactants.

Answer 1

1. The value of K is much greater than 1 and more products form than reactants.

This is the case since the value of ∆G is negative. This tells us the reaction is spontaneous and thus the K value will be >1 which means more products than reactants will form.
