A reversible elementary reaction takes place inside a closed, highly thermally conductive container of constant volume, whose reactants are all gases. Given the reaction equations and the reaction rate constants, a natural question to ask is how the concentration of each gas changes w.r.t. time. In this article, I will answer this question by proposing a general approach to solve it.

This article gives the formula for the normal vectors of a surface defined by a scalar field on Rn. The normal vector of the graph of the function y=f(x) at (x0,f(x0)) is (∇f(x0),−1). This also provides us a way to recover a scalar field from the normal vectors of its graph: normalizing the vectors so that the last component is −1, and then integrate the rest components.
