Butadiene, C4H6, in the gas phase undergoes a reaction to produce C8H12. The following data were obtained for the reaction.
[C4H6] Time (min)
Determine the order of the reaction.
Order with respect to [C4H6] = 2
Calculate the rate constant for the reaction.
k = .00102 M-1min-1
How long does it take for the initial concentration to decrease by one-half?
t1/2 = 980 min
How long does it take for half of the initial concentration to decrease by one-half?
Second t1/2 = _____ min
I do not understand how to get the second t1/2. Please help. Thanks.
Your question is not complete. If it is about the rate law and/or the rate law constant, k, look ate 2nd example here:
