Question

what is order of reactivity in chemistry??​

Answer 1

Explanation:

The reactivity series lists metal compounds, including magnesium sulphur and lead, in their order of reactivity, with the least reactive at the top. Those at the top and bottom are most keen to react with other elements to form compounds. Less reactive metals will displace other metals from their compounds.

Answer 2

Answer:

definition: The order of chemical reaction is defined as the sum of the powers of the concentration of the reactants in the rate equation of that particular chemical reaction.

Consider a general reaction:

aA +bB→cC+dD

suppose the rate for this reaction is:

-r↓a=k A^xB^y

here x and y indicate how sensitive the rate is to the change in concentration of A and B. Hence, the order of this reaction is x+y.

Note that x and y may not respectively correspond to the            stoichiometric (measure of elements) coefficients of A and B.
