Decomposition of A is a first order reaction at

\mathrm{T}(\mathrm{K})

and is given by

\mathrm{A}(\mathrm{g}) \rightarrow \mathrm{B}(\mathrm{g})+\mathrm{C}(\mathrm{g})

. In a closed 1 L vessel, 1 bar

\mathrm{A}(\mathrm{g})

is allowed to decompose at

\mathrm{T}(\mathrm{K})

. After 100 minutes, the total pressure was 1.5 bar . What is the rate constant (in

\min ^{-1}

) of the reaction ? (

\log 2=0.3)

6.9 \times 10^{-1}

6.9 \times 10^{-3}

6.9 \times 10^{-2}

6.9 \times 10^{-4}
