A negative order means that as the concentration of that substance is increased, the rate of the reaction decreases. An example of this would be a product with a negative order. If the concentration of this product is increased, it participates in a reverse reaction, thereby slowing down the reaction rate.

WebMay 12, 2024 · The rate of reaction is negative when it is defined by a reactant. Rate of reaction can be defined in many ways, but the most common way is to measure the change in concentration of a species of the reaction over time. If the concentration of reactant is measured, it will decrease over time as it is consumed and so the rate will be recorded … WebAug 11, 2024 · 2. Orders of reaction are experimental parameters. So they cannot be predicted in advance. They can be 0, 1, 2 or 3.
