For an exponential relationship to exist in nature there must be a physical mechanism that causes a variable to change at a rate that is directly proportional to its own value. Explain why the voltage on a capacitor discharging through a constant resistance exponentially decays with respect to time

After the switch has been closed for a long time, so that the capacitor is completely charged, the switch then opens so that the capacitor discharges through the membrane resistor. This models "repolarization" of the axon. Here, after the potential of the inside the axon as compared to the outside becomes quite large and positive, the membrane becomes more permeable to potassium ions, which then rush from the inside of the axon (top...

The questions I need help with are in bold
[Resistance-Capacitance] = [Resistance] middot [Capacitance] = volta/amp middot coulomb/volt = coulomb/volt = change/change/time = time. Thus, the dimensions of RC are the dimensions of time. Since RC is also a constant, tau = RC is called the 'time constant' of the circuit.) This constant is an important one: it controls the rate of discharge of the capacitor (through the resistor). Because delta V(0) = RI, the voltage across the capacitor is...

b) Electrochemistry is the branch of physical chemistry that
studies the relationship between electricity, as a measurable and
quantitative phenomenon, and identifiable chemical change, with
either electricity considered an outcome of a particular chemical
change or vice versa. These reactions involve electric charges
moving between electrodes and an electrolyte (or ionic species in a
solution). Thus electrochemistry deals with the interaction between
electrical energy and chemical change. When a chemical reaction is
caused by an externally supplied current, as in...
