For the reaction: c2h4br2 + 3 ki → c2h4 + 2 kbr + ki3, when the rate of disappearance of c2h4br2 is 2.0 × 10-5 m/s, what is the rate of disappearance of ki?

The value of the rate disappearace of KI is

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

The rate in terms of reactants is given as negative as the concentration of reactants is decreasing with time whereas the rate in terms of products is given as positive as the concentration of products is increasing with time.

Given:

Putting in the values we get:

Rateof disappearace of KI=

Thus the value of the rate disappearace of KI is

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
