15.23
a) A -> B, given that the concentration of A decreases to one-half its initial value in 1000s determine the rate constant expressed for the rate loss of A ... I feel like this is simpler than the question is making it seem but I'm getting confused, can someone tell me how to go about this?

Re: 15.23
Since this is a first order reaction, we can use the first order half life equation
t_(1/2)=ln 2/k
We know that the half-life is 1000s, so what we need to do is calculate for k
k=ln 2 /t_(1/2)=0.693/1000 s = 6.93x10^-4 s^-1
t_(1/2)=ln 2/k
We know that the half-life is 1000s, so what we need to do is calculate for k
k=ln 2 /t_(1/2)=0.693/1000 s = 6.93x10^-4 s^-1
