Question
1 mole of A , 1.5 mole of B and 2 moles of C are taken in a vessel volume one litre. At equilibrium concentration of C is 0.5 mole/L. Equilibrium constant for the reaction
A (g) + B (g) = C (g)
Joshi sir comment
A (g) + B (g) = C (g)
1 1.5 2
1-x 1.5-x 2+x
according to the given condition 2+x = 0.5 so x = -1.5
now calculate Kc
