Question
Consider a second order reaction in which reactant "A" decomposes according to the chemical equation 2A = products.
The data given is the time, in minutes, and the corresponding change in the concentration of reactant "A" for this reaction.
t (min)
1) 0.00
2) 20.0
3) 40.0
4) 60.0
5) 80.0
[A] t (M)
1) 0.500
2) 0.382
3) 0.310
4) 0.260
5) 0.224
For a second order reaction, the rate constant "k" is the slope of the graph of 1 / [A] versus "t". Based on this information and the data given, calculate the rate constant "k" for the reaction. Express your answer in M^-1 * min^-1 to three significant figures.
The rate constant "k" = ______________ M^-1 * min^-1
Explanation / Answer
We know that for second order reaction
1 / [A]f - 1 / [A
