The correct answer for this question is this one:
As shown in the graph, The curved part of this figures is a semicircle.
What is the area of this figure?
28+8.125π units²
<u>28+16.25π units²</u>
14+8.125π units²
14+16.25π units²
Hope this helps answer your question and have a nice day ahead.
<span>Assuming the reaction is of 1st order, we can
start using the formula for rate of 1st order reaction:</span>
dN / dt = k * N
Rearranging,
dN / N = k dt
Where N = amount of sample, k = rate constant, t = time
Integrating the equation from N = Ni to Nf and t = ti to
tf will result in:
ln (Nf / Ni) = k (tf – ti)
Since k is constant, we can equate to situations.
Situation 1 is triple in size every days, situation 2 is after 20 days.
ln (Nf / Ni) / (tf – ti) = k
ln (3Ni / Ni) / 4 = ln (Nf / 40) / 20
Calculating for Nf,
<span>Nf =
