Since the pressure of a gas is directly proportional to the concentration of gas, we can express the rate law for a gaseous reaction in terms of partial pressures. Using the above data, deduce the rate law, the integrated rate law, and the value of the rate constant, all in terms of pressure units in atm and time in seconds. Predict the pressure of $\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}$ after $900 . \mathrm{s}$ from the start of the reaction. (Hint: To determine the order of the reaction with respect to $\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}$, compare how the pressure of $\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}$ decreases with each time listing.)
