If the order of a chemical reaction with respect to one of its reactants is zero how does that reactant's concentration affect the rate of the chemical reaction?
It doesn't - the reaction rate will not change regardless of how much of that reactant is added. That's the definition of zero-order.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
A catalyst increases the rate of a chemical reaction by changing which of the following conditions?
A catalyst can speed up the rate of a given chemical reaction by lowering the activation energy required for the reaction to occur. However, the catalyst does not change the total free energy from reactants to products.
Why does breaking the object in many pieces affect the rate of chemical weathering?
Grinding or powdering an object increases the surface volume available for chemical interaction. More the reagent is individualized more effecient is the reaction with it's environment.
What are the four factors that affect the rate of a chemical reaction?
Whether a catalyst is present or not, Concentrations of reactants, Temperature, Pressure (but this is least likely to affect rate)
What is a material that slows down the rate of a chemical re action?
In general, a material that decreases the rate of a chemical reaction is called an inhibitor.
A what is a material that slows down the rate of a chemical reaction?
An inhibitor decreases the reaction rate
What is the difference between a catalyst and an inhibitor?
Catalyst: a substance which promote and help a chemical reaction. Inhibitor: a substance which greatly reduces the rate of a chemical reaction.
What material slows down the rate of chemical reaction?
Inhibitor~a material used to decrease the rate of reaction
How does an increase in temperatre affect chemical reaction?
Increases reaction rate.
How does concentration affect the rate of a chemical reaction?
Increasing the concentration of the reactants increases the rate of the reaction.
Compare and contrast a catalyst and an inhibitor?
Catalysts increase the rate of reaction while Inhibitors decrease it. They both affect the rate of reaction, hence giving us more control over our reaction.
What is the name of substance that slows reaction?
The substance that slows down a chemical reaction is an inhibitor. Instead you could also call an inhibitor an anticatalyst.-anticatalyst `antee'katlist1. (chemistry) a substance that retards a chemical reaction or diminishes the activity of a catalyst
Will introducing a competitive inhibitor change the rate of reaction?
It slowed the reaction rate down
A material that decreases the rate of reaction?
Inhibitor
What material is used to decrease the rate of a reaction?
An "inhibitor" (aka negative catalyst) slows or blocks a chemical reaction. In some cases this can also be called a deterrent or a retardant. The term anticatalyst(anti-catalyst) refers to blocking the action of a catalyst.
How does temperature affect the rate of a chemical change?
Changing temperatures has a dramatic affect on the rate of chemical reaction. As an example for every 10 degrees you raise the environment the reaction doubles (to a certain degree)
