question 59

Multiple Choice

Tetrafluoroethylene, C₂F₄, can be converted to octafluorocyclobutane which can be used as a refrigerant or an aerosol propellant. A plot of 1/[C₂F₄] vs. time gives a straight line with a slope of 0.0448 L mol⁻¹s⁻¹. What is the rate law for this reaction?

• A)Rate = 0.0448 (L mol ⁻¹s ⁻¹)[C ₂F ₄]
• B)Rate = 22.3 (mol L ⁻¹s)[C ₂F ₄]
• C)Rate = 0.0448 (L mol ⁻¹s ⁻¹)[C ₂F ₄] ²
• D)Rate = 22.3 (mol L ⁻¹s)[C ₂F ₄] ²
• E)Rate = 0.0448 s ⁻¹ [C ₂F ₄]
