Consider the following data showing the initial rate of a reaction (A→products) at several different concentrations of
[A](M) | Initial rate (M/s) |
0.15 | 0.024 |
0.30 | 0.191 |
0.60 | 1.525 |
Estimate the value of the rate constant, k.
Rate law
Rate = K[A]^x
0.024 = K(0.15)^x -------->1
0.191 = K(0.30)^x ---------> 2
1.525 = K(0.60)^x ---------->3
equation 1 divide by equation 2
0.024/0.191 = K(0.15)^x/K(0.3)^x
0.125 = (0.15/0.3)^x
(0.5)^3 = (0.5)^x
x = 3
Rate law
Rate = K[A]^3
0.024 = K(0.15)^x -------->1
0.024 = K(0.15)^3
K = 0.024/(0.15)^3 = 7.11 M^-2 s^-1 >>>answer
The rate constant = 7.11 M^-2 s^-1 >>>answer
Reactions within the table are 2nd order reactions, giving us the equation of:
rate = k[A]2
I will be using experiment 1
Given:
rate = 0.024
k = ?
[A] = 0.15
Therefore, 0.024 = k[0.15]2
k = 1.06 M-1s-1
