Question

Given the reaction

Answer 1

From the calculation, the equilibrium constant is obtained as 3. Option A

What is the equilibrium constant?

The term equilibrium constant shows the extent to which we could see the conversion of the reactants to products in a reaction system. Now we know that the equilibrium constant can be obtained by the use of the formula;

K = [H2] [I2]/[HI]^2

Now we have that at equilibrium;

[H2]  = 0.5 M

[I2] = 1.5 M

[HI] = 0.5M

It then follows that;

K = 1.5 * 0.5/( 0.5)^2

K = 3
