In chem class, we‘re studying the reaction between a constant amount of dolomite (magnesium carbonate) and 50cm3 of dilute hydrochloric acid.Would the rate of reaction be faster or slower if only 25cm3 of acid was used?
U could are attempting ester hydrolysis utilizing acid catalyst,right here using different conc of HCl u may just show the effect of conc;furthermore by carrying out the reaction at exclusive temp might exhibit the temp dependance of a primary order response
Raising the car and putting on bigger tires reduces fuel economy. What you would end up with is a crappy handling dangerous mess that gets lousy mileage. Backyard engineering is just that.
My shop can fab a lift kit for almost any vehicle out there. We built one for a Buick Rondezvous which is about the same as the Vibe. Where are you located?
mgco3+2hcl------mgcl2+co2+h20 now rate [mgco3][hcl]^2 now we see that if we change conc. of hcl say double in your case half reaction becomes 1/4 times i.e decreases
As long as in both cases there is sufficient acid to totally cover the dolomite , and the acid is always in excess, then rate of reaction is unchanged. You change the rate of reaction by changing the concentration of the acid , not the volume of acid.
