its been a while since i've done and general chem is required for my major. so any help is greatly appareciated.
A student conducted an experiment to determine what factors are important in the rate of a reaction between potassium carbonate and hydrochloric acid. The student diluted 4.000 mL of 4.000 M K2CO3 to 75.00 mL, then combined that solution with 75.00 mL of 2.000 M HCl.
The student tabulated the amount of CO2 gas collected over time.
T (min) Volume (mL)
Use a rearrangement of PV = nRT to solve for the number of moles of CO2 produced. You may assume atmospheric pressure and room temperature.
so I think that n= RT/PV where T = (23 + 273)K, V=75ml, then what? If I can just know how to calculate it for the first min, the rest should be the same - no?
It's just that I have a vague background on molar calculations so not really sure on how start/finish the problem. any help appreciated.
