There are two methods used primarily.
In the first method, the same reaction is repeated several times, but each time a different concentration of the reactants is used and the initial reaction rate is measured each time. However, it must be done in a logical way for this method to work. The simplest way to do it is to start with one ratio of the reactants. Let's assume we have two reactants, A and B. So we'll start with a concentration of 1 for A and 1 for B. Measure the initial rate. Then we'll double the concentration of A to 2, but keep B the same. If the rate doubles, the order of reactant A is one, but if the rate quadruples, the order is 2. Then we do the same thing for B. Keep A the same, but double B. Again, does it double or quadruple the rate? If you have three reactants you have do do more combinations like this to isolate each variable. Just make sure you change only one thing at a time so you can figure out individual effects. If you change everything at once, it's a mess!
The other way is to look at the reaction rate as a function of time. Here the reaction is only performed once, but the rate is monitored over time. Based on the predictions for different order reactions, the shape of the curve you plot when you graph the reaction rate versus time will be different for different order reactions. By the shape of the graph you plot, you can tell the reaction order in this way.

What two ways that you can measure reaction rate?
Reaction rate can be measured by monitoring the change in concentration of reactants or products over time, typically using techniques such as spectrophotometry or titration. Alternatively, reaction rate can also be assessed by measuring the change in physical properties, such as gas volume or pressure, if a gas is produced or consumed during the reaction. These methods provide insights into how quickly a chemical reaction occurs under given conditions.
What is the reaction order with respect to b?
The reaction order with respect to a reactant, such as b, refers to the exponent to which the concentration of that reactant is raised in the rate law expression for a chemical reaction. It indicates how the rate of the reaction depends on the concentration of b. For example, if the rate law is given as rate = k[b]^n, then the reaction order with respect to b is n. This order can be determined experimentally through methods such as the method of initial rates or integrated rate laws.
What measures of how fast reaction occurs?
The measure is the rate of reaction.
Methods for determination of reaction mechanism?
Monitoring reactant disappearance or product formation over time using techniques such as UV-Vis spectroscopy or chromatography can provide insight into reaction intermediates. Isotope labeling experiments can help identify the pathway of a reaction by tracing the fate of specific atoms during the reaction. Computational chemistry methods, such as density functional theory calculations, can be used to predict reaction pathways and intermediate structures. Kinetic studies, including determining rate laws and activation energies, can provide information about the steps involved in a reaction mechanism.
What type of reaction is Anger is what type of physical reaction?
Anger is typically characterized by a physical reaction known as the "fight or flight" response. This response triggers the body to release stress hormones like adrenaline, leading to increased heart rate, heightened alertness, and readiness to act aggressively or to flee from a perceived threat.
What are the methods for the determination of rate of reaction?
In this method we determine the rate of reaction physically.in this method we put the sample in machine and thus we determine the reaction rate.it is very easy method.
How do you determine the rate of a reaction?
There are several physical and chemical methods depending upon nature of reactants and products.
What experimental methods can be used to determine the specific rate constant, k, for a chemical reaction?
Experimental methods that can be used to determine the specific rate constant, k, for a chemical reaction include the method of initial rates, the method of integrated rate laws, and the method of isolation. These methods involve varying the concentrations of reactants, measuring the rate of reaction at different conditions, and analyzing the data to determine the rate constant.

What methods can you use to increase the rate of a chemical reaction?
There are several ways that the rate of reaction may be increased. Some of the more common ways areincrease temperatureincrease surface area (grind or powder the reactants)use a catalystagitate/stir the reaction mixture
What are you measure when you use kinetic methods?
Kinetic methods measure the rate at which a chemical reaction occurs. This can include monitoring changes in concentration over time, determining reaction rates, and assessing reaction mechanisms based on how fast reactants are consumed or products are formed.
What factors influence the rate constant in a chemical reaction?
The rate constant in a chemical reaction is influenced by factors such as temperature, concentration of reactants, presence of catalysts, and the nature of the reactants and their physical state.
Why calculate initial rate of reaction from a curve rather than measure how much gas is released?
Calculating the initial rate of reaction from a reaction curve allows for a precise determination of the reaction rate at the very beginning, providing insights into the mechanism of the reaction. In contrast, measuring how much gas is released over time gives information about the overall extent of the reaction but may not reflect the actual rate at the start due to factors like gas buildup or reaction completion.
What measures of how fast reaction occurs?
The measure is the rate of reaction.
What is the speed at which a reaction occurs called?
The chemical term is reaction rate.
