Question

For the reaction

A + B ⇌ C

The value of equilibrium constant is 100 at 298 K. If the initial concentration of all the three species is 1 M each, then the equilibrium concentration of C is x × 10^–1 M. The value of x is .....(Nearest integer)

Answer 1

Answer is : 25

x = \(\frac{3}{4}\)

[C]eq. = 1 + 2x

= 1 + 2 \(\Big(\frac{3}{4}\Big)\)

= 2.5 M 

25 x 10^–1 M
