Question

4) The isomerization reaction, CH3NC CH3CN, is first order and the rate consta 0.46 s-1 at 600 s 0. 30 M? Remember the integrated law of a first order reaction is In[AVTAo] --kt. concentratio K. What is the concentration of CH3NC after 0.20 minutes if the initial nt is equal to years. What is the decay 5) The decay of C-14 is a first order and the half- life of carbon-14 is 5715 constant k of carbon-147 6) Answer the following questions based on the reaction profile of the ozone formation below a) What is the b)

Explanation / Answer

ln A = -kt + ln Ao

k = rate constant

t = time

Ao = Initial concentration

A = concentration at time t

Question 4

k = 0.46 sec-1 =  0.007666 Min-1

ln A = -kt + ln Ao

ln A = -0.46 x 12 + ln 0.3

ln A = - 0.00153332 -1.203

A = 0.0012 M

Question 5

Decay constant = 0.693 / k = 0.693 /5715 year = 1.212 x 10-4 Year -1
