I don’t understand how to write this equation.

Write an equation relating the concentration for a reactant A at t=0 to that at t=t for a first-order reaction. Define all the terms, and give their units. Do the same for a second- order reaction.

Yes, I think so. For first order,
ln(Ao/A) = akt; therefore, for t = 0, we have ln(Ao/A) = 0
(Ao/A) = 1
and A = Ao = 1

Then I believe you are to use the original with t for t, and solve for (A).

Same thing with second order but more challenging mathematically.
