The half-life formula for a first-order reaction is t1/2=0.693/k, where k is the rate constant. The given rate constant is 0.693/5 s^-1, which equals approximately 0.139 s^-1. Substituting that value into the formula gives t1/2=0.693/0.139, which equals approximately 5.0 s. Therefore, the correct answer is C, 5.0.

The Half-Life of This Reaction Is __________ S
