Rate Equasions

Question 1

Determination of the order of reaction using concentration time graphs

Answer 1

Known [A]&[B] much larger [B] so effectively constant determine [A] at different times and plot graph

Question 2

Initial rates method of determining the rate equation

Answer 2

(A + B —> C)
Carry out experiments using different concentrations of A and B (change one at a time) plot concentration time graph and measure initial gradient

Question 3

Arrhenius equation

Answer 3

Ae^-ea/RT

A and k have same units (both constants)
