in mathese you are saying......
\(\dot N = \color{red}{-} \color{blue}{k} N\)
the standard/ basic decay equation...
does that make sense ?

Answer 2

ok

Answer 3

should it be dN/dt= - k/N

Answer 5

ah!

i reached for the standard decay equation.....but you are right now that i read the wording..."inversely proportional to the number of atoms present at any time".....

i just wonder if the question is worded correctly cos it doesn't make much sense to me :p

Answer 6

ok yes that's the whole question.

Answer 7

thank you
