Question

The rate constant (k) for the reaction is approximately:

a. 3.05×10−4mol L−1s−1
b. 6.20×10−4mol L−1s−1
c. 1.83×10−4mol L−1s-1
d. 5.68×10−4mol L−1s−1

Answer 1

The rate constant (k) for the reaction is approximately 3.05×10−4 mol L−1 s−1.

Step-by-step explanation:

The rate constant (k) for a reaction can be determined using the units of the rate of reaction, which are mol/L/s. In this case, the units for k should be mol-2L2/s so that the rate is in terms of mol/L/s. Using this information, we can compare the given options to find the closest match:

a. 3.05×10−4 mol L−1 s−1

b. 6.20×10−4 mol L−1 s−1

c. 1.83×10−4 mol L−1 s−1

d. 5.68×10−4 mol L−1 s−1

Based on the units and values given, the closest match is option a. 3.05×10−4 mol L−1 s−1.
