A bituminous coal has the following analysis: \( 74.4 \% \mathrm{C}, 5.1 \% \mathrm{H}, 1.4 \% \mathrm{~N}, 6.7 \% \mathrm{O}, 0.7 \% \mathrm{~S} \) and \( 11.7 \% \) ash. It is burned with excess air to generate electricity power in a power station at the feed rate of \( 50 \mathrm{~kg} / \mathrm{s} \). The temperature of the flue gas is \( 1100 \mathrm{~K} \). Assuming that the molar ratio of \( \mathrm{NO} \) to \( \mathrm{NO}_{2} \) in the flue gas is \( 1: 1 \), and they are the only forms of NOx present in the flue gas. If \( \mathrm{NH}_{3} \) is to be injected to the flue gas to control \( \mathrm{NOx} \), how much \( \mathrm{NH}_{3} \) would be required per day (assuming no excess \( \mathrm{NH} 3 \) is required). At \( 1100 \mathrm{~K} \) : \[ \begin{array}{l} 2 \mathrm{NO}_{2}+4 \mathrm{NH}_{3}+\mathrm{O}_{2} \rightarrow 3 \mathrm{~N}_{2}+6 \mathrm{H}_{2} \mathrm{O} \\ 4 \mathrm{NO}+4 \mathrm{NH}_{3}+\mathrm{O}_{2} \rightarrow 4 \mathrm{~N}_{2}+6 \mathrm{H}_{2} \mathrm{O} \end{array} \] Select one: a. \( 100.16 \) ton/day b. \( 990.16 \) ton/day c. \( 120.16 \) ton/day d. \( 110.16 \) ton/day Clear my choice
