# How do you calculate the rate constant? watch

1. Hi

Theres a question in the chemical ideas book for OCR B and its asking to calcule the constant, k.

How would i go on about calculating the constant?
2. you need initial rate and the rate concentrations of all components and rearrange to get k to get on its own, and then cancel to get units

I'm confused.
4. Probably better for you to give a little more info as it really does depend on what you've been given

However commonly determining from the rate equation:

rate = k[A][B]

if you have rate and the concentrations of A and B then: k = rate/([A][B])

It's a very long question, but from the formula you have given i understand how to work it out now
thanks
