Given the reaction 2NO2 1/202 N2O5, what is the relationship between the rates of formation of N,0, and disappearance of the two
daser333 [38]

Answer:

r=\frac{r(NO_{2})}{2} =\frac{r(O_{2})}{1/2}=\frac{r(N_{2}O_{5})}{1}

Explanation:

Let us consider the reaction:

2 NO₂ + 1/2 O₂ ⇄ N₂O₅

The rate of formation of a substance is equal to the change in concentration of the product divided the change in time:

r(N_{2}O_{5})=\frac{\Delta [N_{2}O_{5}] }{\Delta t}

The rate of disappearance of a reactant is equal to to the change in concentration of the reactant divided the change in time, with a negative sign so that the rate is always a positive variable.

r(NO_{2})=-\frac{\Delta[NO_{2}] }{\Delta t}

r(O_{2})=-\frac{\Delta[O_{2}] }{\Delta t}

The rate of the reaction is equal to the rate of any substance divided its stoichiometric coefficient. In this way, we can relate these expressions:

r=\frac{r(NO_{2})}{2} =\frac{r(O_{2})}{1/2}=\frac{r(N_{2}O_{5})}{1}

Rate law equation The rate of a chemical reaction depends on the concentrations of the reactants. For the general reaction betwe
Studentka2010 [4]

Explanation:

In the following reaction;

aA+bB⇌cC+dD

A and B are the reactants while C and D are the products.

a, b, c and d are regarded as coefficients.

The dependence of the reaction on the concentration of the reactants is given by the rate law.

This is given by;

rate= k [A]^m [B]^n

where

K = Rate constant. Constant for the reaction at that temperature.

m = order of reeaction with respect to A

n = order of reaction with repsect to B

Overall order of reaction is given by m + n
