Attainment of the equilibrium A(g) 2C(g) + B(g) gave the following graph. Find the correct option. (% dissociation = fraction dissociated × 100)

At t = 5 sec equilibrium has been reached and K c = 128 (mol/liter) 2

At t = 5 sec equilibrium has been reached and % dissociation of A is 60%

At t = 5 sec equilibrium has been reached and % dissociation of A is 40%

None of these

Text Solution

Verified by Experts

The correct answer is:

K p = 0.800 atm maximum pressure of CO 2 in the container to calculate maximum volume of container the 0.8 atm and none of CO 2 should get converted into CaCO 3 (s).

so V (0.800 atm) = (10 L) (0.2 atm)

so v = 2.5 L
