Rate from Time Taken Calculator

🔑 Enzymes & reaction rates. Use the Rate from time taken formula to find rate, time taken: pick the value you want, type the others, and the answer updates as you go.

rate=1000t\text{rate} = \dfrac{1000}{t}

Used when you time how long something takes, like starch disappearing (iodine stops turning blue-black).

Worked example

Find the rate when Time taken = 40 s.

Using rate = 1000/t: Rate = 25 s⁻¹.

Frequently asked questions

What is the formula for Rate from time taken?

rate = 1000/t. Used when you time how long something takes, like starch disappearing (iodine stops turning blue-black).

What do the letters stand for, and what units are used?

Rate in s⁻¹, Time taken in s.

How do you calculate rate?

Put the values into rate = 1000/t. For example, with Time taken = 40 s, rate = 25 s⁻¹.

Can I solve for a different value?

Yes. In the calculator above, pick the circle next to any value (rate, time taken) and fill in the others: it rearranges the formula for you.
