In a reaction A+2B hArr 2C, 2.0 moles of 'A' 3 moles of 'B' and 2.0 moles of 'C' are placed in a 2.0 L flask and the equilibrium concentration of 'C' is 0.5 mol // L . The equilibrium constant (K) for the reaction is

For the reaction, A(g)+2B(g)hArr2C(g) one mole of A and 1.5 mol of B are taken in a 2.0 L vessel. At equilibrium, the concentration of C was found to be 0.35 M. The equilibrium constant (K_(c)) of the reaction would be

X_2(g)+Y_2(g) hArr 2XY(g) reaction was studied at a certain temperature.In the beginning, 1 mole of X_2 was taken in a one litre flask and 2 moles of Y_2 was taken in another 2 litre flask and both these containers are connected so that equilibrium can e established.What s the equilibrium concentration of X_2 and Y_2 ? Given Equilibrium concentration of [XY]=0.6 moles/litre.
