Answer:
The rate determining step is step 1
Explanation:
According to the chemical equation, the ratio between Ca and HCl for a complete reaction is 1:2. The moles of Ca can be calculated by mass/molar mass, thus 60.0 g/40 g/mole = 1.5 mole. So the moles of HCl in the solution is 1.5mole*2 = 3 mole.
So the volume of HCl solution = Moles of HCl/ concentration of HCl = 3 mole/ 1.25 M = 2.4 L = 2400 mL
