Question

The reaction, Y \(\rightarrow\) Product is of first order with the initial concentration of Y = 3.55 \(\times\) 10\(^{−3}\) moldm\(^3\) and the rate constant of 5.25 \(\times\) 10\(^{−3}\)s\(^{−1}\). What is the half-life of the reaction?

Options

A) 350s

B) 215s

C) 132s

D) 615s


The correct answer is C.

Explanation:

\( t_{1/2} = \frac{ln(2)}{k} =\frac{0.693}{5.25 \times 10^{-3}} = 132s \)
