To solve for the rate constant, we can rearrange the rate law:
rate = k[H2][I2]
Plugging in the given values:
0.660 M/s = k(0.54 M)(0.52 M)
Simplifying the equation:
0.660 = k(0.2808)
Dividing both sides by 0.2808:
k = 0.660 / 0.2808 ≈ 2.35 M^-2s^-1
Rounding this value to two significant digits:
k ≈ 2.4 M^-2s^-1
The rate of a certain reaction is given by the following rate law:
rate=k[H2][I2]
Use this information to answer the question below.
The rate of the reaction is measured to be 0.660 M / s when [H2] = 0.54 M and [I2] = 0.52 M. Calculate the value of the rate constant. Round your answer to 2 significant digits.
