rates

we did a practical at college today
Mg + 2HCL -> MgCl2 + H2
using different concentration of HCl to see how concentration effects rate.
I have the volume of H2 produced per 10 sec for 3 mins and concentration of HCl
A question says to plot concentration against rate, I don't understand what it means by plotting rate? I dont have any values for this?

Do you have the volume/mass of any of the substances?

volume of HCl solution, and its conc ans volume of H2 produced

plotting rate is like for example, how much of it is produced per second, right?
in this case, are you trying to find out how much H is produced every 10 seconds maybe?

Is the H placed in only one concentration?

Have I got the completely wrong idea? aha

try that. If it gives you how much H was produced in the first 10 seconds, then the first uot of the ten little squares on a graph represents 1second. rate would be ...g/s at that point
