Decomposition Can Be Modeled Using the Following Equation $$m _ { t } = m _ { 0 } \mathrm { e } ^ { - k t }$$

Short Answer

Decomposition can be modeled using the following equation: $$m _ { t } = m _ { 0 } \mathrm { e } ^ { - k t }$$ where m_t is the mass of leaf litter that remains at a particular time, m₀ is the initial mass of leaf litter, k is the daily decomposition rate, and t is time in days.
Using a decomposition rate (k) of 0.15, how long would it take for 100 g of leaf material to degrade 75 percent?
