The half-life for the second-order decomposition of HI is 15.4 s when the initial concentration of HI is 0.67 M. What is the rat
larisa [96]

Answer:

The correct answer is option C.

Explanation:

Half life for second order kinetics is given by:

t_{\frac{1}{2}=\frac{1}{k\times A_0}

t_{\frac{1}{2} = half life = 15.4 s

k = rate constant =?

A_0 = initial concentration = 0.67 M

15.4 s=\frac{1}{k\times 0.67 M}

k=\frac{1}{15.4 s\times 0.67 M}=0.09692 M^{-1} s^{-1}=9.69\times 10^{-2}M^{-1} s^{-1}\approx 9.7\times 10^{-2} M^{-1} s^{-1}

9.7\times 10^{-2} M^{-1} s^{-1}  is the rate constant for this reaction.
