ln[A] = -k(t) + ln [A] make k subject

Question

ln[A] = -k(t) + ln [A]

 

make k subject

Answer 1

Hi Amnike,

 

I think you want to solve for k?

 

ln[A] = -k(t) + ln[A]

 

-kt + ln[A] = ln[A] just flipping the equation about the equal sign

 

-kt = ln[A] - ln[A]

 

We know from the rules of logarithms that ln[x] - ln[y] = ln[x/y] for any x,y real numbers. So,

 

-kt = ln[A/A]

 

-kt = ln[1]

 

But ln[1] = 0.

 

-kt = 0

 

So, k = 0  Maybe?
