At 593k a particular decomposition’s rate constant had a value of 5.21×10−4 and at 673k the same reaction’s rate constant was 7.42×10−3. it was noticed that when the reactant’s initial concentration was 0.2264 m (with a 593k reaction temperature), the initial reaction rate was identical to the initial rate when the decomposition was run at 673k with an initial reactant concentration of 0.05999 m. recall that rate laws have the form rate = k [a]x and, showing work, determine the order of the decomposition reaction.

The order of the decomposition reaction is 2.

Explanation:

Rate constant of reaction at 593 K , =

Rate constant of reaction at 673 K , =

Rate of the reaction at 593 K =

Initial concentration of reactant = [A] =  0.2264 M

...[1]

Rate of the reaction at 673 K =

Initial concentration of reactant = [A'] =  0.05999 M

...[2]

(given)

x = 1.999 ≈ 2

The order of the decomposition reaction is 2.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
