Indium -112 is radioactive and has a very short half-life (`t_(1//2)=14` min). Its decay constant and average life are repectively:
a) 0.0495 `"min"^(-1)`, 9.7 min
b) `0.495 "min"^(-1)`, 20.2 min
c) `9.7 "min"^(-1)`,20.2 min
d) `0.0495 "min"^(-1)`,20.2 min

Options

A. 0.0495 `"min"^(-1)`, 9.7 min
B. `0.495 "min"^(-1)`, 20.2 min
C. `9.7 "min"^(-1)`,20.2 min
D. `0.0495 "min"^(-1)`,20.2 min

Answer

D
