The decomposition reaction: 3A(g) → 2B(g) + 2C(s) follows first-order kinetics. Starting with pure 'A' (at 6 atm), the pressures of system after 20 min and after a very long time are 5.05 atm and 4.05

Question

The decomposition reaction: 3A(g) → 2B(g) + 2C(s) follows first-order kinetics. Starting with pure 'A' (at 6 atm), the pressures of system after 20 min and after a very long time are 5.05 atm and 4.05 atm, respectively. Identify the correct statement(s) related with the reaction.

Prashant Kotian · Accepted Answer

Correct answer: C,D. From the answer key and calculating the first-order kinetics based on pressure drop, options C and D correctly match the respective completion times and system pressure. Therefore, correct answer is C,D.
