Why was it necessary in all kinetic runs to keep constant the total volume of the reagents after mixing

Homework Answers

Answer #1

Volume of reactants should be kept constant to do a fair test and comparison of results.eg. If you are testing for the effect of increasing surface area, the volume of reactants should be kept constant.

Other reason is because reactions can be concentration dependent. Side reactions producing by-products can be favored if a reaction is performed either more dilute or more concentrated than optimal. Yes, reaction volume does relate to concentration since concentration is in g/mL.

adiabatic container with a total volume of 10 ft3 is initially evacuated. You would like to input air from a supply line, which runs at a temperature of 100oF and a pressure of 50 psia, by opening a valve that lets the air get into this container. Calculate the amount of air that you got in the container, in lbm. Can this happen? Assume constant heat capacities.
