The reaction, 2A(g) + B(g)hArr3C(g) + D(g) is begun with the concentration of A and B both at an intial value of 1.00 M. When equilibrium is reached, the concentration of D is measured and found to be 0.25 M. The value for the equilibrium constant for this reaction is given by the expression:

In an experiment the equilibrium constant for the reaction A+BhArr C+D is K_(C) when the initial concentration of A and B each is 0.1 mole. Under similar conditions in an another experiment if the initial concentration of A and B are taken to be 2 and 3 moles respectively then the value of equilibrium constant will be
