1 points Save Answer QUESTION 3 2A B C The above reaction is run and found to follow second order kinetics with a rate constant of 1.30 x 3 M-1sec-1. f the initial concentration of 1.54 M, the concentration after 172 seconds? 1 points Save Answer QUESTION 4 2A B C indicates that The above reaction is run and it is found that a plot of the concentration of A versus time is linear as the reaction proceeds. This the reaction is zero order in Al O first order in [A] second order in Al third order in LA]

Explanation / Answer

3)

for second order reaction

1/[A] = Kt + 1/[A0]

1/[A] = 0.0013 x 172 + 1/1.54

1/[A] = 0.2236 + 0.65

1/[A] = 0.8736

[A] = 1.14 M

answer = 1.14 M
