The Arrhenius equation relates the rate constant to:
A.Concentration and temperature
B.Temperature and activation energy
C.Pressure and volume
D.Moles and mass
Explanation
Core Concept
The Arrhenius equation k = Ae^(-Ea/RT) shows that the rate constant k depends on the activation energy (Ea), temperature (T), and the frequency factor (A).
Correct Answer
BTemperature and activation energy
