Knowing the rate of absorption

Postby ursulavictorino1K » Tue Mar 17, 2020 12:43 am

How can you figure out the rate of formation of one element if you know the rate of absorption of another element?

Elements are consumed and formed in nuclear reactions.

If you mean, compounds in chemical reactions, and you also mean rate of change in compound concentration, then look at the balanced chemical equation.

For example: A ---> 2B

The rate of formation of B is twice the rate at which A is consumed because only one A is used to form two B.

Refer to the Unique Rate in a chemical equation and it'll tell you how the rate of absorption for a reactant is related to the rate of formation of the product. It all depends on the stoichiometric coefficient.

For the equation aA + bB -> cC + dD, where a,b,c,d are coefficients, the rate of absorption of A and the rate of formation of C are related as such:
(1/a)(d[A]/dt) = (1/c)(d[C]/dt)
