Gaseous decomposition of

A

follows

I^{st}

order kinetics. Pure

A (g)

is taken in a sealed flask where decomposition occurs as

A (g) \to 2 B (g) + C (g)

After

10

sec., a leak was developed in the flask. On analysis of the effused gaseous mixture (Obeying Graham's law) coming out initially, moles of

B

were found to be double of

A

. What is rate constant in
