What is the unit of slope obtained from Arrhenius equation?(slope=-Ea/2.303R)
Correct answer: C. K
- A. K¯
- B. J/mol K
- C. K
- D. Mol/K
Explanation
The slope is given by -Ea/2.303R. The units for activation energy or Ea are Jmol−1 and those for R are JK−1mol−1. By dividing Ea by R, K is obtained which is the unit of the slope.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
