Question

1) You conduct a Vitamin C Clock Reaction at 298 K using the following initial concentrations:

Concentration of Vitamin C = 0.0023 M

Concentration of Iodide = 0.032 M

Concentration of Hydrogen Peroxide = 0.18 M

If the reaction time is 27 seconds, please calculate the reaction rate

		6.7 x 10-3 M∙s–1
		1.2 x 10-3 M∙s–1
		4.9 x 10-7 M∙s–1
		8.5 x 10-5 M∙s–1

2) You determine that x = 1 and y = 1 for the rate law of the Vitamin C Clock Reaction.

For one trial of the lab conducted at 298 K, you gather the following information:

Reaction Rate = 3.2 x 10^–5 M∙s^–1

Concentration of Iodide = 0.032 M

Concentration of Hydrogen Peroxide = 0.088 M

Please calculate the reaction constant (k) for this trail using Equation 5.

		880 M-1∙s–1
		3.6 x 10-4 M-1∙s–1
		1.0 x 10-3 M-1∙s–1
		0.011 M-1∙s–1
