What is n in these reactions? is it the electrons?

The number of moles.

If you're talking about kinetics n is the order of the reactant.

It's essentially the order of the reaction that is determined by the concentration of reactants.

n represents the order of the reactant, which in turn gives insight into the mechanism of the reaction.

How can we calculate n and m?

how do you know what the order is

For the electrochemistry section, n represents the number of electrons transferred. You can find this by balancing the half reactions.

n is the number of moles of electrons you have in your half reactions

n is the number of electrons transferred. In order to calculate n, you must write the half reactions for reduction and oxidation, balance them, and then see the number of electrons transferred.

In kinetics, n refers to the order of the reactants in a reaction. If n=1, this tells us the rate is directly proportional to the concentration of [reactant].

remember when given a table with the concentration of reactants and rates of different reactions, the order can be found by setting up a ratio of the concentration from (ex.) (Conc. Experiment 1 / Conc. Experiment 2)^n = (Rate Experiment 1 / Rate Experiment 2). Remember that the variables that represent order are applied to the concentration, not the experimental rates! Hope this helps.

how do you know what the order is

The order refers to the sum of all the exponents of the concentrations in the rate law. For example, if the rate law was rate=kr[A]^2[B]^3, the overall order would be 5. However, it is important to keep in mind that the order of each individual species only refers to that species’ specific coefficient and is therefore different (unless it’s the only reactant affecting the rate).

For kinetics, n is the exponent that a concentration is raised to in a rate law, the sum of these exponents is the overall order of the reaction. In the homework problems you can find n based off of given experimental data that shows the variation of rates with concentrations of reactants.

If you are referring to kinetics when you say "these reactions", then n is just the order of the reaction. The order of the reaction can give you a basic understanding of how the reaction works (reaction mechanism).
