For the reaction, H ₂( ~g )+ I ₂( ~g ) 2 HI ( ~g ) Attainment of equillibrium is predicted correctly by :

Correct answer

1

Step-by-step solution

H ₂( ~g )+ I ₂( ~g ) 2 HI ( ~g ) Concentrations of H ₂( ~g ) and I ₂( ~g ) decrease with time while concentration of HI ( g ) increases with time. At equilibrium H ₂( ~g ), I ₂( ~g ) and HI ( g ) attain constant values. Correct plot of molar concentration with time is
