Reaction rates are determined by performing chemical experiments. The expression will be specific to the reactants and products in a particular chemical reaction, and will include a constant known as k and a number of terms that include the concentrations of particular reaction components. Some or all of these reactant terms may be raised to an exponential power higher than one. As an example, when reacting hydrogen gas and nitric oxide, the reaction rate will be the constant k multiplied by the concentration of hydrogen gas multiplied by the concentration of nitric oxide squared. For this reaction, increasing the amount of nitric oxide present will have more of an effect on speeding up the reaction than adjusting the amount of hydrogen.

What describes a reaction that reaches equilibrium?
The product and reactants reach a final, unchanging level.
Which equation represents a combustion reaction?
A combustion reaction is a reaction that burns. The equation that represents a combustion reaction is CH4 + 2O2 reacts to yield CO2 + 2H2O.
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
Could heat increase the rate of reaction?
if reaction is exothermic then on heating rate of reaction wil be low,and if reaction is endothermic then rate of reaction wil be high on heating
During dynamic equilibrium how do forward reaction rate and reverse reaction rate compare?
Equilibrium at this point means that the forward reaction and the backward reaction are taking place at the same rate. The formation of the products and the reactants are at equal rate.
What is the rate of the of a reaction?
An expression relating the rate of a reaction to the rate constant and the concentrations of the reactants
What is the rate of a chemical reaction is?
An expression relating the rate of a reaction to the rate constant and the concentrations of the reactants
What is the difference between rate of reaction and chemical equation?
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
How can you tell whether an expression represents a unit rate?
Either the numerator, or more likely the denominator, of the ratio representing the expression is 1.
Does the rate of reaction equal surface area over volume?
No. There is no one single expression for the rate of a chemical reaction. It depends on many factors. It is true, however, that the greater the surface area, the greater would be the rate of reaction, but it isn't EQUAL to SA/Volume.
What is formula of Ostwald?
The Ostwald equation is a mathematical expression that describes the relationship between the rate of a chemical reaction and the concentration of the reactants. It is typically used in the context of reactions that follow first-order kinetics and is mathematically represented as: rate = k[A], where rate is the reaction rate, k is the rate constant, and [A] is the concentration of the reactant A.
What measures of how fast reaction occurs?
The measure is the rate of reaction.
What do you mean by specific reaction rate of a reaction?
The rate constant include all parameters ((but not concentration) affecting the rate of a chemical reaction.The expression "specific reaction rate" is used when the molar concentration of reactants is a unit.
What is the speed at which a reaction occurs called?
The chemical term is reaction rate.
Which expression represents the area of a trapezoid?
answer
What describes a reaction that reaches equilibrium?
