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

Options

  1. A0.182
  2. B1.818
  3. C1.182
  4. D0.818

Correct answer

B. 1.818

Step-by-step solution

aligned & 100= (1+x)(1+x) (1-x)(1-x) & 1+x 1-x =10 & 1+x=10-10 x & 11 x=9 & x= 9 11 =0.818 aligned (D) 1+x=1+0.818=1.818
