Homework Help: chemistry

today, i did a lab on the molar volume of hydrogen gas. in this experiment, we poured around 10 mL of hydrocholric acid into a gas collection tube with water and measured the volume of gas to be around 20.9 mL.
would changing the molarity of the hydrochloric acid affect the final results? explain.

no, it would change the rate of the reaction is all. I assume you had an excess of acid. Now if you did not have an excess of acid, that is another matter.

yes we did.
so would it slow or speed up the rate of the reaction?

if you dilute, it slows it down.
