Sublimation is an example of a zero-order reaction. Provide other examples, and explain why the reactant available for reactions is unaffected by changes in the overall quantity of the reactants.

Expert Solution

the law velocity shows the relationship between the velocity of the reaction with the velocity constant and the reactive concentration. To a general reaction

aA + bB ------- cC + dD

and the velocity law is

V = k [A]^x [B]^y

X and Y not correspond with stequiometric values, and it could be enter number, fraction or even negative number, and the sum of the give us the order of reaction

When we have an order 0, it means that it doesn't matter the concentration of the reactants the velocity only will be influenced by k the constant of velocidad. So it doesn'tmatter if we reduce on half the concentration or double it the velocity will always be the same.

Some examples could be:

2NH3 (g) ------------- N2(g) + 3H2 (g)

It doesn't matter the amount of NH3 that is present the volocity of the change of NH3 to N2 won't change.

The reaction of 0 order its easily found in heterogenic catalysis, when the reaction is carried on a surface saturated with the reactive. And in reactions with enough excess of substrate to saturate the catalyst.
