Question

Equilibrium constant has no unit, when the number of moles on both sides are equal,but it has a unit when the number of moles on both sides are not equal, why? Because if number of moles are not equal then there is no equilibrium,and if there is no equilibrium then how equilibrium constant can exist? correct answer please please,I will Mark as brainliest​,it's very urgent please​

Answer 1

Answer:

Equilibrium does not mean the no. of moles in both side is/are equal. It means a state when the rate of forward reaction and backward reaction is same. It does not mean same amount of reactants and products.

let,   H2 + I2   ◄────────►  2HI  ,it is a reaction in equilinrium state. No. of mole of reactants and products are same , 2.

Again,  CO + 3H2  ◄───────► CH4 + H2O, it is also a reaction in equilibriun state. But no. of mole of reactants (4) and no. of mole of products (2) are not same

If number of moles are not equal then there may be equilibrium state. So, Equilibrium constant can exist also.
