Question

For the reaction, \[ H_2(g) + I_2(g) \rightleftharpoons 2HI(g) \]

Attainment of equilibrium is predicted correctly by: 


 
 

• A. A
• B. B
• C. C
• D. D

Hint:

At equilibrium, the concentrations of reactants and products become constant, and the reaction rate of the forward and reverse reactions become equal.

Answer 1

The Correct Option is C

- For the reaction at equilibrium, the concentrations of the reactants (\( H_2 \) and \( I_2 \)) decrease, and the concentration of the product (\( HI \)) increases over time. - As the system reaches equilibrium, the concentration of the reactants will stabilize and the product concentration will also stabilize. Thus, the graph where the concentrations of \( H_2 \) and \( I_2 \) decrease and the concentration of \( HI \) increases correctly represents the attainment of equilibrium. Final Answer: Option (3).
