Chemical EquilibriumHard

Question

For the system : P(s) ⇋ 2Q(g) + 3 R(g)
keeping the temperature constant equilibrium is some how disturbed such that at new equilibrium, concentration of R is increased by a factor of 2. At new equilibrium concentration of Q changes to-

Options

A.2 times its original value
B. times its original value
C. times its original value
D. times its original value

Solution

KC = [R]03 [Q]02
Temperature is constant hence Kc is also constant
At new eq.
Kc = [2R]3 [Q]2
Q′ = Q0
