An oil tanker breaks apart and starts leaking. As time goes on, the rate at which the oil is leaking out will diminish. Suppose that $t$ hours after the tanker breaks apart, the oil is leaking out at a rate of $R(t) = \frac{0.4}{1+t^2}$ million gallons per minute. Then million gallons of oil will leak out in the first 9 hours after the shipwreck. Be careful with units.

4. Methane ($CH_4$) is combusted in the presence of 20% \"excess air\" (which means that > stoichiometric amount of $O_2$ is provided). Assume combustion is complete and that the $N_2$ in the air stream passes through the combustion system unaffected. Air composition 21% oxygen and 79% nitrogen gas a. Calculate the mole ratio of $N_2$ to $O_2$ in the supplied air. b. Write the reaction under stoichiometric conditions for $CH_4$ reacting with $O_2$ to produce $CO_2$ and $H_2O$. Also account for the fact that $N_2$ is present in the system (spectator). c. Write the reaction under 20% excess air conditions. d. Determine the composition of the exhaust gas under excess air conditions (i.e., the mole fraction of each species in the exhaust gas).
