Question

A+B = C + D. K for this reaction is 10. If 1, 2, 3, 4 moleflitre of A, B, C and D respectively are present
in a container at 25°C, the direction of reaction will be​

Answer 1

Answer:

It proceeds forward.

Explanation:

Given reaction

A + B ---------->C + D

It's reaction constant(k) is

K=[C][D]/[A][B]

Given [A]=1 mol/lit

          [B]=2 mol/lit

          [C]=3 mol/lit

          [D]=4 mol/lit

Therefore K=(4)*(3)/(1)(2)

K=6 at equilibrium K=10

so K should increase from 6 to 10.

Hence the concentrations of C and D should increase since they are in numerator in calculating the expression for K.

Hence the concentration of products should increase,

i.e The direction of reaction should be forward.
