question 22

Multiple Choice

The Arrhenius equation, $k = A e ^ { - E _ { \mathrm { u } } / R T }$ expresses the dependence of the rate constant on the reaction temperature. The slope of a plot of ln(k) versus 1/T is equal to

• A) \(\frac { - E _ { a } } { R T }\)
• B) \(- E _ { a }\)
• C) \(E _ { a }\)
• D) \(\ln ( A )\)
• E) \(\frac { - E _ { a } } { R }\)
