reaction rate depends upon three things: temperature (higher temperature means faster reactions), particle size (smaller particles leading to an increase in surface area means faster reactions) and concentration of reactants (the higher the concentration, the higher the chance for particle collisions).
Rate of reaction is based upon particle collisions. Higher temperatures yield more and stronger collisions, hence there is higher rate of reaction.
Smaller particles (giving more surface area) means more collisions (reactants are not "stuck" on the inside of clumps of substances, waiting to collide when the outer particles get out of the way).
Higher concentrations let more particles find each other to react; time is not wasted by substances floating around not having a chance to collide with other substances.

What of the following is necessary to determine the rateof the reaction using the rate law?
To determine the rate of the reaction using the rate law, you need the rate equation that relates the rate to the concentrations of reactants. It is also essential to have experimental data, such as the initial rates of reaction at different concentrations of reactants, to determine the rate constant and the order of the reaction with respect to each reactant.
What the rate law how do concentrations affect rate?
The rate law is an equation that relates the reaction rate to the concentrations of reactants, typically expressed in the form Rate = k[A]^m[B]^n, where k is the rate constant, [A] and [B] are the concentrations of the reactants, and m and n are the reaction orders. The concentration of reactants affects the rate of a reaction; generally, an increase in concentration leads to an increase in the reaction rate, as there are more particles available to collide and react. However, the specific relationship depends on the order of the reaction with respect to each reactant.
How to find the partial pressure at equilibrium in a chemical reaction?
To find the partial pressure at equilibrium in a chemical reaction, you can use the equilibrium constant expression and the initial concentrations of the reactants and products. Calculate the equilibrium concentrations of each species using the stoichiometry of the reaction and then use these concentrations to determine the partial pressures.
How do you calculate the equilibrium constant for a chemical reaction?
To calculate the equilibrium constant for a chemical reaction, you divide the concentrations of the products by the concentrations of the reactants, each raised to the power of their respective coefficients in the balanced chemical equation. The resulting value represents the equilibrium constant for the reaction.
How is the equilibrium constant of a reaction determined?
Molarity of products divided by reactants Keq=(products)/(reactants)
How does the rate law show how concentration charges affect the rate of reaction?
The rate law expresses the relationship between the rate of a chemical reaction and the concentrations of the reactants raised to specific powers, known as the reaction orders. Each concentration term in the rate law indicates how changes in that reactant's concentration affect the reaction rate; for instance, if a reactant has a reaction order of 2, doubling its concentration will quadruple the reaction rate. This mathematical relationship allows chemists to predict how varying the concentrations of reactants will influence the speed of the reaction. Overall, the rate law quantitatively illustrates the impact of concentration changes on reaction kinetics.
What does the rate law tell you about a reaction?
The rate law is an equation that relates the rate of a chemical reaction to the concentration of reactants. It provides information on how the rate of the reaction is influenced by the concentrations of reactants and any catalysts involved. Additionally, the rate law helps determine the specific reaction order for each reactant.
Which is necessary to determine the rate of a reaction using the rate of law?
To determine the rate of a reaction using the rate law, you need the rate constant (k), the concentrations of the reactants, and the reaction order with respect to each reactant. The rate law expresses the relationship between the rate of the reaction and the concentrations of the reactants raised to their respective powers, which correspond to the reaction orders. Experimental data is required to establish these parameters accurately.

What is the general form of a rate equation for a reaction involving two reactant A and B?
The general form of a rate equation for a reaction involving two reactants A and B can be expressed as ( \text{Rate} = k[A]^m[B]^n ), where ( k ) is the rate constant, ( [A] ) and ( [B] ) are the concentrations of reactants A and B, respectively, and ( m ) and ( n ) are the reaction orders with respect to each reactant. The values of ( m ) and ( n ) are determined experimentally and can be whole numbers or fractions. This equation reflects how the rate of the reaction depends on the concentrations of the reactants.
What do you mean by equilibrium constant?
It is the ratio of the concentrations of products to the concentrations of reactants.
What is necessary to determine the rate of a reaction using the rate law?
To determine the rate of a reaction using the rate law, you need to know the rate constant (k), the concentrations of the reactants, and the order of the reaction with respect to each reactant. The rate law equation relates the rate of the reaction to these factors.
