If KC > 10x, the products predominate over reactants. Then what is the value of x?(a) 2(b) 3(c) 4(d) 1I have been asked this question in an online interview.This interesting question is from Applications of Equilibrium Constants topic in division Equilibrium of Chemistry – Class 11

Answer»

Right choice is (b) 3

To EXPLAIN I would say: If KC > 10x, the products are PREDOMINANT, over the reactants in a chemical reaction because if KC is very large the reaction proceeds nearly to completion an example for this is at 300K,H2(g) + Cl2(g) \(\rightleftharpoons\) 2HCL(g), KC = 4 X 10^31.
