The reaction is at equilibrium. Option C
The term equilibrium constant refers to a value that shows the extent to which reactants are converted into products in the reaction.
We know that;
∆G =∆G'° + RT In Keq
∆G'° = −4.40 kJ/mol
R = 8.314 J/K/mol
T = 25 + 273 = 298 K
Thus;
∆G = −4.40 * 10^3 + (8.314 * 298 * ln[2.90 * 10^-3/0.490 * 10^-3]
∆G = −4.40 * 10^3 + 4.40 * 10^3
∆G = 0
Hence, the reaction is at equilibrium.
