For the following chemical reaction:

A + B --C.

Three students measure the initial reaction rate, but under different conditions (initial concentration of substances A and B).

Student [A] [B]
1
2
3 0.20 M
0.20 M
0.40 M 0.20 M
0.40 M
0.40 M

The rate constant for this reaction, at a certain temperature, is 2.5 M-1s-1 (assume it is first order with respect to both reactants):

Which student observed the reaction which proceeded the quickest?
What is the rate of the quickest reaction?
