A reaction rate is a measure of how fast a chemical reaction occurs. It is typically expressed as the change in concentration of a reactant or product per unit of time. Understanding reaction rates is crucial in many fields, including chemistry, chemical engineering, and environmental science, as it helps predict how quickly reactions will proceed under different conditions.

var initialConcentration = parseFloat(document.getElementById("initialConcentration").value);

}
// The rate of reaction is the change in concentration over the change in time.
// Rate = (Δ[Reactant]) / Δt
// Since reactant concentration decreases, we use the absolute change.
var concentrationChange = Math.abs(finalConcentration – initialConcentration);
