Answer
$$\frac{\Delta [ClO_2]}{\Delta t} = 0.052 \ M/s$$
b) is the correct answer
Work Step by Step
- Write the rate expressions:
$$rate = -\frac{\Delta [F_2]}{\Delta t} = - \frac{1}{2}\frac{\Delta [ClO_2]}{\Delta t} =\frac{1}{2}\frac{\Delta [FClO_2]}{\Delta t} $$
$$-\frac{\Delta [F_2]}{\Delta t} = - \frac{1}{2}\frac{\Delta [ClO_2]}{\Delta t} $$
$$-0.026 = - \frac{1}{2}\frac{\Delta [ClO_2]}{\Delta t} $$
$$0.026 * 2 = \frac{\Delta [ClO_2]}{\Delta t} $$
$$\frac{\Delta [ClO_2]}{\Delta t} = 0.052 \ M/s$$
