. Consider the following equilibrium
At the approach of equilibrium, concentrations of A, B and C are 0.5 M, 3M and 1.5M respectively. At the start of the reaction, C was absent but D was present (initial concentration of D = 0.5 M). Identify the correct statement:
A. Kc = 25 M2
B. the concentration of D at equilibrium is 4.5 M
D. addition of helium at constant pressure to the equilibrium mixture would push equilibrium backward
Addition of inert gas at constant pressure shifts the equilibrium towards greater moles.
