In an experiement things that are changing are called variables.
Moles of Li2CO3 = 1.53/73.891 = 0.0207 mole
Since HCl is in excess, amount of CO2 will depend on the limiting reagent which is Li2CO3.
∴Moles of CO2 = Moles of Li2CO3 = 0.0207.
The answer to that question would be Activation energy. If would like me to elaborate just let me know. :)
