Explanation / Answer

(a)

Initial number of molecules of A = 30

At equilibiruim,

number of molecules of A = 30 - x

number of molecules of B = x

Then,

Kc = [Product]/[Reactant]

5.0 = x / (30-x)

150 - 5x = x

6x = 150

x = 150/6

x = 25

So, at equilibrium,

Number of molecules of A = 30 - x = 30 - 25 = 5

and number of molecules of B = 25

(b)

At equilibrium, number of molecules of A = 30 -x and B = x

Kc = [Product]/[Reactant]

0.50 = x / (30 - x)

15 - 0.5 x = x

1.5x = 15

x = 10

So, at equilibrium number of molecules of A = 30 - 10 = 20

numberr of molecules of B = 10
