(a) The reaction $\mathrm{H}_{2} \mathrm{O}_{2}(a q) \longrightarrow \mathrm{H}_{2} \mathrm{O}(l)+\frac{1}{2} \mathrm{O}_{2}(g)$ is first order. Near room temperature, the rate constant equals $7.0 \times 10^{-4} \mathrm{~s}^{-1} .$ Calculate the half-life at this temperature. (b) At $415^{\circ} \mathrm{C},\left(\mathrm{CH}_{2}\right)_{2} \mathrm{O}$ decomposes in the gas phase, $\left(\mathrm{CH}_{2}\right)_{2} \mathrm{O}(g) \longrightarrow \mathrm{CH}_{4}(g)+\mathrm{CO}(g) .$ If the reaction is first order with a half-life of 56.3 min at this temperature, calculate the rate constant in $\mathrm{s}^{-1}$.

A sample of radioactive material with decay constant 0.08 is decaying at a rate \( \mathrm{R}(\mathrm{t})=-2 e^{-0.08 \mathrm{t}} \) grams per year. How many grams of this material decayed after the first 14 years? Write the definite integral that will be used to estimate the decay. The definite integral that will be used is \( \int_{0}^{\square} \square \mathrm{dt} \). Approximately \( \square \) grams of this material decayed after the first 14 years. (Round to the nearest hundredth as needed.)
