Question

1. The decomposition of N2O4 to NO2 is carried out
at 280°C in chloroform. When equilibrium is
reached, 0-2 mol of N204 and 2 x 10-3 mol of
NO2 are present in a 2L solution. The equilibrium
constant for the reaction N204 2 NO2 is
(A) 1 X 10-2 (B) 2 x 10-3
(C) 1 x 10-5 (D) 2 x 10-5.​

Answer 1
