`H_2(g)+l_2(g)iff2Hl(g)`, This reaction is carried in a 2 litre flask taking 0.4 mol `H_2` and 0.4 mol `l_2`. At equilibrium if 0.5 mol Hl is produced then calculate the value of equilibrium constant `K_c`.

1 mol PCl_(2)(g) is heated in a closed container of 2 litre capacity. If at equilibrium, the quantity of PCl_(5)(g) be 0.2 mol then calculate the value of equilibrium constant for the given reaction, PCl_(5)(g)hArr PCl_(3)(g)+Cl_(2)(g) .

Ethyl acetate is formed by the reaction between ethanol and acetic acid and the equilibrium is represented as: CH_(3)COOH(l)+C_(2)H_(5)OH(l)hArr CH_(3)COOC_(2)H_(5)(l)+H_(2)O(l) (1) Write the concentration ration (reaction, quotient), Q_(c) , for this reaction (note: Water is not in excess and is not a solvent in this reaction). (2) At 293K, if one starts with 1.00 mol of acetic acid and 0.18 mol of ethanol, there is 0.171 mol of ethyl acetate in the final equilibrium mixture. calculate the equilibrium constant. (3) Starting with 0.5 mol of ethanol and 1.0 mol of acetic acid and maintaining it at 293K, 0.214 mol of ethyl acetate is found after sometime. has equilibrium been reached?

The reaction A(g)+4B(g)hArr2C(g)+3D(g) is carried out in a closed vessel of volume 2L by taking 3 mol of A(g) and 4 mol of B(g ). At equilibrium, if the amount of C(g) be 1 mol. then K_c for the reaction 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.
