Question

How do you determine the units for the rate constant?

Answer 1

it depends on the order of the reaction

Answer 2

What if it is a fourth order reaction

Answer 3

Zero order -> \(M^1 s^{-1} = M/s \)
First order --> \(M^0 s^{-1} = 1/s \)
Second order ->\( M^{-1} s^{-1} = L/mol* s\)

can you see the pattern?

Answer 4

But why is mols there for the second order???

Answer 5

because of the nature of the equation

rate=\(k[X]^2\), you'll end up with /mol

Answer 6

Ooooooooooh I seee! Thank you very much :) You are very helpful!

Answer 7

no problem, dude! glad i could help
