What is the effect on the rate of a chemical reaction when the concnetration of a reactant is decreased?
When the concentration of the reactant is decreased, the rate of chemical reaction go slow.
What happens to the reaction rate when reactant particles are able to collide more often and with more energy?
The reaction rate increases when reactant particles are able to collide more often and with more energy.
How does an increase in reactant concentration affect the rate of reaction?
It leads to more frequent collisions, which increase reaction rate.
What physical factors control the rate of chemical reactions?
Surface area of the reactant.
What happens to a reaction as the reactant are used up?
The rate of the reaction slows down
What happen to the reactant rate as a reactant gets used up?
The rate goes down.
If you double a concentration of a reactant then the rate of the reaction doubled The order with respect to the reactant is?
First order; the rate is directly proportional to the concentration of reactant.
What happens to the reaction rate as a reactant gets gets used up?
The rate goes down.
What is the effect on the rate of a chemical reaction when the concnetration of a reactant is decreased?
When the concentration of the reactant is decreased, the rate of chemical reaction go slow.
What happens to the reaction rate as the reactants get used up in a reaction?
The rate of a reaction begins to decreases as reactant are used up
What is the rate equation if it is 3rd order in reactant A and 2nd order in reactant B?
rate=k[A]^3[B]^2 thats A cubed and B squared
What must be known for the rate constant to be calculated for the rate law?
The reaction rate at known reactant concentrations.
What must be known for the rate constant to be calculated from the rate law?
The reaction rate at known reactant concentrations.
What happens to the reaction rate as reactant gets used up?
The rate goes down.
What is the definition of a reactant concentration?
Reactant concentration is the exponent or index in which a substance's concentration term is increased in the rate equation. Reactant concentration is also known as the order of reaction.
Does the mass of a solid reactant affect the reaction rate?
yes it does
How will decreasing reactant concentration affect the reaction rate?
Decreasing the reactant concentration will slow the rate of the reaction. If you use the idea of adding oxygen and hydrogen to make water and decease the amount of one, you will produce less water. It doesn't matter which reactant is less as there are just are not enough to go around.
