Show explicitly how we arrived at the conclusion that $i_o = nFAkC_O^{1-\alpha}C_R^{\alpha}$, where $i_o$ is the exchange current, $F$ is the Faraday's constant, $A$ is the electrode area, $k$ is the apparent rate constant, $C_O$ is the concentration of oxidize species, $C_R$ is the concentration of reduced species, and $\alpha$ is the transfer coefficient.

Question 4: Find the general solution of the differential equation: $e^{-y}(1+y') = 1$. Determine the integration constant using the initial condition $y(0) = -\ln(4)$. Present the particular solution subject to this initial condition in the explicit form (think in which form the explicit solution can be presented $y(x)$ or $x(y)$?).

Question 3: Your employer, Initech, has had their building mysteriously burn down. Since you are out of work, you decide to pursue your dream of raising rabbits. The bank requires a business plan to lend you the money. They would like you to accurately project how many rabbits you will have $n$ years from now. 1 Your initial loan can buy 19 rabbits (i.e. $f(0) = 19$). Each year each rabbit produces 9 more rabbits. Each year 9 of your rabbits are eaten by foxes at the end of the year after they have produced their rabbits. For example, at the end of the first year, you have 19 (initial rabbits) + 19x9 (new rabbits) - 9 (rabbits eaten by foxes) = 181. (a) Develop a recursive expression for the growth of your rabbit population. (b) Prove to the bank that you can determine the rabbit population of a given year $n \ge 0$ using the closed form $f(n) = 18 \cdot 10^n + 1$, $\forall n \ge 0$. In other words, prove that $f(n) =$ $18 \cdot 10^n + 1$, $\forall n \ge 0$ is the closed form of the recursive expression for the growth.
