Question

Only need the answer to #8 Given the reaction A rightarrow B please provide the average rate for molecule A and molecule B. Additionally show that the formation of B and decomposition of A obey the conservation of energy/mass. Also please graph how the concentration of A and B change with time. 7) Assume that the following reaction given enough time will go to completion and never achieve chemical equilibrium. Given the reaction 2O_3(g) rightarrow 3O_2(g), what is the rate in terms of either molecule. If Delta[O_2]/Delta t = 2.66 times 10^-5 M/s what is the rate of disappearance for ozone (O_3). Correct units for full credit Rate = k[A]^m[B]^n[C]^p, where all m = 1 n = 0 and p = 1/2. What is the overall order of the reaction? Given the following information answer the following. An experiment consists of set of 5 experiments taken at 0, 10, 20, 30 and 40 minutes. The concentration of species A was determined via absorption spectroscopy and the results for the respective times are 0.065 moles, 0.051 moles, 0.042 moles, 0.036 moles, and 0.031 moles. a) Plot the data given. What does the plot graphically show. Label properly.

Explanation / Answer

Given:

rate = k [A]m [B]n [C]p

given m = 1, n= 0 p = 1/2

overall order of a reaction = sum of order with respect to individual reactants

= sum of power of Concentrations of reactants in the rate law

= n + m + p = 1 + 0 + 1/2

Overall order of reaction = 1.5 Answer
