Arrhenius Equation

Question 1

State the Arrhenius equation

Answer 1

k=Ae^-(Ea/RT)

Question 2

Rearrange to the form Y= c + mX

Answer 2

ln(k)= -Ea/RT + ln(A)

Question 3

Rearrange to make T the subject

Answer 3

T=Ea/R*(ln(A) - ln(k)

Question 4

Rearrange to make A the subject

Answer 4

A= k/e^-(Ea/RT)

Question 5

Rearrange to make Ea the subject

Answer 5

Ea=RT(ln(A)-ln(k)

Question 6

To make ln(A) the subject

Answer 6

ln(A)= Ea/RT + ln(k)

Question 7

If you plot the graph using this equation, ln(k)= -Ea/RT + ln(A), what would the gradient be?

Answer 7

ln(k) versus 1/T would result in the gradient being Ea/R
