Question

Consider the reaction $N₂(g) + 3H₂(g) \rightleftharpoons 2NH₃(g)$ in a continuous flow reactor under steady-state conditions. The component flow rates at the reactor inlet are $F°_{N2} = 100$ mol/s, $F°_{H2} = 300$ mol/s, $F°_{inert} = 1$ mol/s. If the fractional conversion of $H₂$ is 0.60, the outlet flow rate of $N₂,$ in mol/s, rounded off to the nearest integer, is _________
