Unformatted text preview: Δ G. Consider the reaction quotient: If Q is very large, then Δ G is very large and positive. I.e. the reverse reaction is spontaneous, and the pressure of the product will tend to fall We see that changing the value of the pressure of a reactant will change the sign of Δ G. e.g. If P becomes large, then Q becomes small, so Δ G becomes large and negative To find if the specific minimum pressure of a reactant that changes the sign of Δ G, solve for Q in eqn (1) above; then solve for P reactant in eqn (2)...
