Under some conditions, the concentration of a drug at time \( t \) after injection is given by

\[ C(t) = a \left( C_0 - \frac{a}{b} \right) e^{-bt} \]

Here \( a \) and \( b \) are positive constants and \( C_0 \) is the concentration of the drug at \( t = 0 \). Determine the steady-state concentration of a drug, that is, the limiting value of \( C(t) \) as \( t \to \infty \).

\[ C_s = \, \]

Determine the time \( t \) at which \( C(t) \) is one-half the steady-state concentration.

\[ t = \, \]
