For the reaction, H2(g) + I2(g) ⇋ 2HI(g) Attainment of equilibrium is predicted correctly by:

Question

For the reaction,

\(H_2(g)+ I_2(g) \rightleftharpoons 2HI(g)\) 

Attainment of equilibrium is predicted correctly by:

(1)

(2)

(3)

(4)

Answer 1

Correct option is : (2)

\(H_2+ I_2 \rightleftharpoons 2HI\) 

Concentration of \(H_2\) and \(I_2\) decreases untill equilibrium condition and concentration of HI increases till equilibrium condition and after equilibrium concentration of all the reactant and products remain constant.
