400\,^{\circ}\text{C}

the equilibrium constant for the reaction

H_2(g) + I_2(g) \rightleftharpoons 2\,HI(g)

K_c = 54.3

. In a particular experiment the system is found to have

Q_c = 10.0

at this temperature. (i) Determine the sign of

\Delta G

for the mixture at that instant. (ii) Determine whether the net reaction will proceed in the forward or reverse direction to reach equilibrium.
