Question

(b) If the equilibrium constant for the given reaction is 80.

H2 + I2 2 HI

Predict the direction of reaction when the concentration of [H2] = [I2] = [HI]= 2×10-2 Mol L-1​

Answer 1

Answer:

H

2

(g)+I

2

(g)⇌2HI(g)

Applying law of mass action,

K

c

=

[H

2

][I

2

]

[HI]

2

Given : [H

2

]=8.0 mol L

−1

, [I

2

]=3.0 mol L

−1

,[HI]=28.0 mol L

−I

So, K

c

=

(8.0)×(3.0)

(28.0)

=32.66

Explanation:

ans is 32.66
