The equilibrium constant at 298 K for a reaction A + B ⇌ C + D is 100 . If the initial concentration of all the four species were 1 M each, then the equilibrium concentration of D (in mol L - 1 ) will be:

Step-by-step solution

K at 298   K for the reaction A + B   ⇌ C + D is 100 . Given: The initial concentration of all four species is 1   M . A + B ⇌ C + D t = 0 1 1 1 1 at   equilbrium 1 - x 1 - x 1 + x 1 + x K = 1 + x   1 + x 1 - x   1 - x = 100 ⇒ 1 + x 1 - x = 10 ⇒ x = 9 11 = 0.818 ⇒ D = 1 + x = 1 + 0.818 = 1.818
