Can someone explain what the components of the equation (C = C0e-kt) are please? I've searched google but I can't find anything.
Q) After a one year storage period, an aqueous drug solution with an initial concentration of 5% (w/v) was shown by analysis to have a concentration of 45 g L-1. The drug solution is known to be ineffective if it decomposes to 70% of the initial concentration.
Assuming first order kinetics of decomposition (C = C0e-kt), calculate the shelf life (in months) of the drug solution.
