please help thank you?

Question

in studying the reaction: 2N2O5g-->4NO2g+O2g,
the initial concentration of N2O5 was 0.64mol/L. after 30 minutes into the reaction, all the N2O5 has reacted.
A) what is the average rate of the reaction in the time interval of 30 minutes?
B) is it correct to assume, based on the balanced equation, the rate equation is:
R=k[N2O2]^2
C) suppose the reaction is determined by measuring the rate of decrease of N2O5 concentration,
-change(N2O5)/change temperature, and simultaneously by the rate of increase of NO2 concentration, which rate will come out higher and by what factor?

Answer 1

A) .64 - 0
DIVIDED BY
30 - 0
EQUALS
.0213333333

B) NO the [N2O2] doesnt necessariy have to be squared

C) umm idk sorry.
