How does orientation and the activated complex affect a reaction?
Orientation affects the likelihood of successful collision between reactant molecules, increasing the chance of forming the activated complex. The activated complex is a high-energy, unstable intermediate state in a reaction, which is crucial for the reaction to proceed and for products to be formed. The orientation of molecules influences how effectively they can overcome the activation energy barrier to form the activated complex and progress to product formation.
How are reactant elements or molecules different than the compound produced in a chemical reaction?
reactant elements and molecules are used in a chemical reaction, they are not mixed or combined or produced in a chemical reaction.
What is the effect on the rate of a chemical reaction when the concnetration of a reactant is decreased?
Decreasing the concentration of a reactant will typically decrease the rate of a chemical reaction, as there are fewer reactant molecules available to collide and form products. This is in line with the rate law, which often shows a direct relationship between reactant concentration and reaction rate.
How are reactant atoms and molecules different to their products atoms and molecules?
Reactant atoms and molecules are the starting materials in a chemical reaction, while product atoms and molecules are the substances formed as a result of the reaction. During the reaction, reactant atoms and molecules are rearranged and transformed into new products with different chemical properties. The number and types of atoms remain the same, but their arrangement and interactions change.
What ties up a reactant and prevents it from undergoing the original reaction?
An inhibitor can bind to a reactant and prevent it from undergoing the original reaction by blocking the active site on an enzyme or interfering with the reaction pathway. This interruption stops the reactant from interacting with other molecules and inhibits the progression of the reaction.
How can one determine the molecularity of elementary reactions?
The molecularity of an elementary reaction can be determined by looking at the number of reactant molecules involved in the reaction. If only one reactant molecule is involved, the reaction is considered unimolecular. If two reactant molecules are involved, the reaction is bimolecular. And if three reactant molecules are involved, the reaction is termolecular.

Molecularity of chemical reaction?
Molecularity of a chemical reaction refers to the number of reactant molecules participating in a elementary reaction step. It provides information about the number of molecules colliding to form products in a single step. For example, a unimolecular reaction involves only one reactant molecule, while a bimolecular reaction involves two reactant molecules.
What is an activated complex?
An activated complex is an intermediate state in a chemical reaction where the reactant molecules are at their highest energy level before forming products. It represents a critical point in the reaction where old bonds are breaking and new bonds are forming.
Why does surface of a reactant influence the rate of the reaction?
A chemical reaction is nothing but the conversion of the reactant molecules into product molecules. By increasing the surface area of the reactants more number of reactant molecules are exposed which eventually increases the rate of the reaction...for example, powdered chalk piece dissolves faster in water than a piece of chalk.
In a chemical reaction what tells you how many atoms or molecules of a reactant or a product take part in a reaction?
A subscript
What happens to the reaction as a reactant gets used up?
As a reactant gets used up in a reaction, the rate of the reaction may slow down since there are fewer reactant molecules available to react. This can lead to a decrease in the production of products until all the reactant is fully consumed.

What causes the reaction rate to decrease as the reaction progresses?
The concentration of the reactants decreases.
