Reaction rate constants are fundamental in [chemical kinetics](https://www.example.com). They quantify the speed at which a chemical reaction proceeds. For example, in a simple first-order reaction, the rate constant \( k \) can be determined using the equation: \[ \text{Rate} = k[A] \] where \([A]\) is the concentration of the reactant. The value of \( k \) can be influenced by various factors including temperature, pressure, and the presence of a [catalyst](https://www.example.com).
