One mole of `H_2`, 2 moles of `I_2` and 3 moles of HI are injected in a one litre of flask. What will be the concentration of `H_2, I_2` and HI at equilibrium when `K_c` is 45.9 ?

In a chemical reaction A + 2B overset(rightarrow)(leftarrow)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 . Calculate the equilibrium constant (k) for the reaction.

8 gm H_2 = _____moles-

0.1 mole of CH_3NH_2 (Kb= 5xx10^-4) is mixed with 0.08 mole of HCl and diluted to 1 L What will be the H+ ion concentration in the solution

2 moles of N_2 and 5 moles of H_2 are mixed in a one litre flask. If 75% of N_2 is converted into ammonia by the reaction N_2(g) + 3H_2(g) iff 2NH_3(g) , then the total number of moles of gas at equilibrium Is :

The equilibrium constant, K_c , for the reaction, H_2(g) + I_2(g) iff 2HI(g) is 56.8 at 800K. When the mixture was analysed, it was found to contain 0.316 mol/L HI at 800K. What are the concentrations of H_2 and I_2 at equilibrium? (Assume that initial concentrations of H_2 and I_2 were the same.)

1:1 mole of A are mixed with 2.2 mole of B and the mixture is kept in one litre flask till the equilibrium is reached A+2Biff2C+D . At equilibrium 0.2 mole of C is formed. The equilibrium constant in presence of catalyst at 2000K is

1 mole N_2 and 3 moles of H_2 are taken in a 4 litre flask. If 0.25% of N_2 is converted to NH_3 at equilibrium and the reaction is N_2(g)+3H_2(g)iff2NH_3(g) . Then calculate the value of K_c under that condition. Prove that for the reaction aA_2(g)+bB_2(g)iffcAB(g) the value of the ratio K_p/K_c is 1 when a+b=c.

At 700 K, CO_2 and H_2 react to form CO and H_2O . For this process K is 0.11. [fa mixture of 0.45 mole of CO_2 and 0.45 mole of H_2 is heated to 700 K, then After equilibrium is reached another 0.34 mole of CO_2 and 0.34 mole of H_2 are added to the reaction mixture. Find the composition of the mixture at the new equilibrium state. (Assume volume to be 1 dm^3 )

If a mixture of 3 mole H_2 and 1 mole of N_2 is completely converted into NH_3 what would be final volume at same P and T.
