Question

At 783 K in the reaction, H₂(g) + I₂(g) ⇌ 2HI(g), the molar concentrations (mol L⁻¹) of H₂, I₂ and HI at some instant of time are 0.1, 0.2 and 0.4, respectively. If the equilibrium constant is 46 at the same temperature, then as the reaction proceeds

(a) the amount of HI will increase

(b) the amount of HI will decrease

(c) the amount of H₂ and I₂ will increase

(d) the amount of H₂ and I₂ will not change

Answer 1

Answer is : (a) the amount of HI will increase

For the reaction,

So, the reaction will proceeds in forward direction. Hence, amount of HI increases.
