Answer 1

Answer:

$k = \frac{2.303}{t} log( \frac{initial \: conc}{final \: conc} ) \\ k \: is \: constant \: so \\ t \: is \: directly \: propotional \: to \: log \frac{a}{f} \\ \frac{30}{t2} = \frac{ log( \frac{100}{25} ) }{ \frac{100}{0.1} } \\ \frac{30}{t2} = \frac{ log(4) }{ log(1000) } \\ t2 = 150$
