The rate constant (k) for a first-order reaction is related to its half-life (t1/2) by the equation: t1/2 = 0.693/k.
Given: \(t_{\frac {1}{2}} = 693\) sec.
Substitute the given half-life into the formula: \(693 = \frac {0.693}{k}\).
To solve for k, rearrange the equation: \( k = \frac {0.693}{693}\).
Performing the calculation: \( k = 0.001\ sec^{-1}\).
The calculated rate constant is \(0.001\ sec^{-1}\).
