Answer 4.3.1: Why we don't need to convert any units first

Problem:

The reaction between propane and hydrogen chloride to form propyl chloride and hydrogen is carried out in a continuous reactor. The product stream is analyzed and found to contain 27.45 mole% C3H7Cl, 27.45 mole % H2 and 14.6% HCl. The feed to the reactor contains only propane and hydrogen chloride. Calculate the fractional conversion of the limiting reactant and the percentage by which the other reactant is in excess. If the molar flow rate of the feed stream is 290 mol/s, what is the extent of reaction? (Give its numerical value and its units.)

Explanation:

We don't need to convert units in the problem because we ony have mole percents and moles given in the problem statment. It's rare for us to be able to avoid doing unit conversions early on in problem statements, but we got lucky here.

Go ahead and go back to the steps to see which other ones might be important in our problem solution.
