4. When 100 ml of 1.0 M HCl is added to 2 g of Na₂CO3 crystals, carbon dioxide
is evolved. All of the following will increase the initial rate of the reaction
EXCEPT
a. addition of 100 mL of 2.0 M HCl instead of 1.0 M HCI.
b. addition of 200 mL of 1.0 M HCl instead of 100 mL.
c. addition of 100 mL of 1.0 M HCl to powdered Na₂CO3 instead of
crystalline Na₂CO3.
d. addition of 100 mL of hot 1.0 M HCl instead of 1.0 M HCl at room
temperature.
e. addition of 200 mL of 2.0 M HCl instead of 100 mL of 1.0 M HCl.
