CHEMISTRY · Single correct · US High School · Chemistry · Atomic Structure & Nuclear · Atomic Structure & Nuclear

Problem

t_{\frac{1}{2}}

, and the decay constant,

\lambda

? (1)

t_{\frac{1}{2}} = \frac{1}{\lambda}

(2)

t_{\frac{1}{2}} = \frac{\lambda}{\ln 2}

(3)

t_{\frac{1}{2}} = \frac{\ln 2}{\lambda}

(4)

t_{\frac{1}{2}} = \ln 2 \times \lambda
