Show your work to receive full credit. You can write your answers on this paper or use a

separate sheet of paper.

The reaction of compound A forming compound $B$ was studied and the following data were

collected. A plot of this data is included on the second page.

a$)$ What is the average rate between $0$ and $1500$ seconds?

b$)$ What is the average rate between $200$ and $800$ seconds?

c$)$ What is the instantaneous rate at $800$ seconds? $($Easiest way

is to use the plot. Draw the line tangent to the curve at $800$

seconds and find the slope of that line.$).$ You do NOT need

to include the graph, but you should indicate which two

points you used to determine the slope of the line.

Consider the reaction: $A(g)+3B(g)2C(g)$

a$)$ Write the equalities that express the relationship between the rate of the reaction with

respect to the changes of concentrations of each of the reactants and products. $($i$.$e$.$

$,$ etc$)$

b$)$ When $C$ is increasing at a rate of $2\mathrm{.}5{10}^{-2}M*s^{-1},$ how fast is $B$ decreasing?

The formation of nitryl fluoride, $N{O}_{2}F,$ is first order in $N{O}_2$ and first order in $F_2.$

$2N{O}_2+F_{2}2N{O}_{2}F$

a$)$ Write the rate law for the reaction.

b$)$ If the concentration of $N{O}_2$ decreases by half, by what factor will the rate of the reaction

change?

c$)$ How will the rate change if the concentration of $F_2$ quadruples and the concentration of

$N{O}_2$ is halved?Rate of decompostition of AKinetics $1$ Homework
