what's the rate of this reaction?

Question

Na2CO3 + H2SO4 --> Na2SO4 + CO2 + H2O

first of all,,is this equation correct?
secondly,, i want to calculate the rate of this reaction,how do i do it?
suggest me an example of the concentrations and volumes of Na2CO3 and H2SO4 to be useful for calculating the rate of this reaction,
the whole experiment should take place within 1 and half hour,,

if this is a difficult one,,can u suggest me a simple but uncommon reaction,in the sense,,uncommon elements but easy to perform and fast,, for calculating its rate,,
now ,,2Na + Cl2 --> 2NaCl,,is so common,,i want an uncommon one,,

don't suggest about sodium and potassium,, my school lab doesn't have it,,

Answer 1

Difficult to get this one slow enough to measure the rate. I suggest CaCO3 + 2HCl ----> CaCl2 + CO2 + H2O. Use marble chips and quite dilute HCl.
You can measure either the mass loss of the reaction vessel (CO2 escaping to the atmosphere) or measure the volume of CO2 every half minute or so, using a gas syringe or an inverted gas collection tube.
