3. When 6 g of granulated Zn is added to a solution of 2 mol/L HCI in a beaker at room temperature, hydrogen gas is generated. For each of the following changes (constant volume of the acid), state whether the rate of hydrogen gas evolution will be increased, decreased, or unchanged. Explain using collision theory. a. 6 g of powdered Zn is used. b. 4 g of granulated Zn is used. c. Temperature is raised to 40°C.
