# What is the relative rate?

I'm a bit confused on what the units, "per second" means.
Is the relative rate (1/t) effectively a decimal of how much of the reaction occurs per second? If so, for example, does this 0.25 s^-1 mean 0.25 of the reaction occurs per second?

Imagine that you work out a rate (by doing 1/t) and get a value of 10 s^-1.

Then you double the conc. repeat and get a value of 20 s^-1. The value has doubled.

We don't actually know the absolute rate in either experiment, but we do know that the relative rate is twice as fast, i.e. doubling the conc. caused one rate to be (relative to the other one) twice as fast.
It might be helpful to think of 'per second' as Frequency, as:

1 s^-1 1 Hz
