Problem

Decomposition of

\text{H}_2\text{O}_2

follows a first order reaction. In fifty minutes the concentration of

\text{H}_2\text{O}_2

decreases from 0.5 to 0.125 M in one such decomposition. When the concentration of

\text{H}_2\text{O}_2

reaches 0.05 M, the rate of [JEE Mains-2016] formation of

\text{O}_2

will be (1)

6.93 \times 10^{-2} \text{ mol min}^{-1}

(3)

2.66 \text{ L min}^{-1}

at STP (2)

6.93 \times 10^{-4} \text{ mol min}^{-1}

(4)

1.34 \times 10^{-2} \text{ mol min}^{-1}
