A mixture initially contains A, B, and C in the following concentrations: [A] = 0.650 M, [B] = 1.35 M, and [C] = 0.300 M. The following reaction occurs and equilibrium is established: A+2B<->C

At equilibrium, [A] = 0.550 M and [B] = 0.400 M. Calculate the value of the equilibrium constant, Kc

The value of for given reaction is 0.465

Explanation:

We are given:

Initial concentration of A = 0.650 M

Initial concentration of B = 1.35 M

Initial concentration of C = 0.300 M

Equilibrium concentration of A = 0.550 M

Equilibrium concentration of B = 0.400 M

For the given chemical equation:

Initial:                0.65     1.35     0.30

At eqllm:        0.65-x   1.35-2x   0.30+x

Evaluating the value of 'x'

So, equilibrium concentration of B = 1.35 - 2x = [1.35 - 2(0.100)] = 1.15 M

Equilibrium concentration of C = (0.30 + x) = (0.300 + 0.100) = 0.400 M

The expression of for above equation follows:

Putting values in above equation, we get:

Hence, the value of for given reaction is 0.465

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
