Reaction {\A}( {\g}) \rightarrow 2 {\B}( {\g})+ {\C}( {\g}) is a first order reaction. It was started with pure A t/min Pressure of system at time t/mm Hg 10 160 \infty 240 Which of the following option is incorrect? [7 Apr 2025 Shift 1]

Correct Answer is : Rate constant of the reaction is 1.693min−1

Partial pressure of A after 10 minute is 40 mm Hg

Initial pressure of A is 80 mm Hg

The reaction never goes to completion

Rate constant of the reaction is 1.693 {\min}^{-1}
