Why is a chemical reaction rate doubled when the concentration of one reactant is doubled explain this in terms of collision theory?

Pretty simple, really. For any one "A" molecule, if there are twice as many of the other "B" molecule present then the odds of it colliding with one of them are twice as high. The same equations for effective collisions hold, so doubling the concentration doubles the reaction rate.

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.
Why does concentration of a reactant influence the reaction rate?
Oxygen!
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.
After a chemical reaction starts when will a chemical reaction end?
When the limiting reactant is completely used up. A limiting reactant is the reactant that determines the amount of product. To determine this use the balanced chemical reaction with the masses of the reactants to determine the moles of product formed. The reactant that forms the least amount of product will be the limiting reactant.
A substance that undergoes change in a chemical reaction is called a what?
A substance that undergoes change in a chemical reaction is called a reactant.
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.
Did a chemical reaction take place if a reactant is smaller?
Yes. If Concentration of a reactant has decreased, that means that that concentration was used in the formation of a product.
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.
How does the concentration of reactant affect the rate of a reaction?
Increasing the concentration increases the molecules' collision frequency.
What are 4 ways the rates of chemical reactions can vary?
Chemical reactions proceed via the formula: R=k[a]x [b]y/[ab]c Where R= reaction rate k= constant [a] = concentration of first reactant [b]= concentration of second reactant [ab]= concentration of product x,y,c = exponential that are unique to every reaction. R therefore varies by: Concentration of reactant a Concentration of reactant b Concentration of product ab Value of reaction constant k Reaction rate can also be affected by temperature but that's an entirely different equation. The Arrhenius equation.
What is the collision theory and how does it relates to reaction rates?
it depends on how high or low the reactant is on the temperature.
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.
What is the difference between a reaction and products of a chemical reaction?
reactant + reactant = product
Why does concentration of a reactant influence the reaction rate?
Oxygen!
Why is a catalyst not a product or a reactant of a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
