Suppose you are given two parallel combustion reactions occurring in a flow reactor:

The reactor is fed with $250$kmo$\frac{l}{h}r{C}_3{H}_8$ and $1500$kmo$\frac{l}{h}r{O}_2.$ The exit stream contains $45$kmo$\frac{l}{h}rC{C}_3{H}_3,165$kmo$\frac{l}{h}$rCO,$450$kmo$\frac{l}{h}rC{O}_2,H_{2}O$ and $O_2.$ Determine the following:
