(Explanation): while you might think that it would be the number of collisions per second, it wouldn't be that because that wouldn't really describe the reaction rate, it would describe the collision rate, which might be different. therefore, a more specific answer would be the speed of the reaction.
Usually, this is called a person's metabolism. People who have very fast metabolisms need more food to maintain healthy cell growth and, subsequently, they usually have more energy than people with slower metabolisms. Slow metabolisms can be a big problem for humans. Because the cells don't need as much food to function, the body stores the huge surplus of nutrients as fat.
In chemistry the rate of equations are understood through equilibrium constants or Kc. The rate of a chemical reaction is the change in product over unit of time.
An expression relating the rate of a reaction to the rate constant and the concentrations of the reactants
It is the number of moles of reactant converted or product formed per unit time.
The rate of a chemical reaction is the speed at which it occurs and goes to completion.
colour change, mass change, titration, clock reaction, etc.
The reaction rate measure the speed or slowness of a chemical reaction.
The reaction rate measure the speed of a reaction.
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
Increasing the temperature of the reactants can increase the rate of the chemical reaction.
Equilibrium, where the rate of the forward reaction is equal to the rate of the reverse reaction.
The enthalpy of reaction is the change of the system enthalpy after a chemical reaction.
The rate of a chemical reaction increase when the concentration of the reactants increase.
The rate of chemical reactions is how long a chemical reaction takes to finish.
The measure is the rate of reaction.
The chemical term is reaction rate.
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
RATE OF REACTION / REACTION RATE definition? don't go to wikipedia...
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
Heat?
With a catalyst the reaction rate is higher.
In general, a material that decreases the rate of a chemical reaction is called an inhibitor.
An expression relating the rate of a reaction to the rate constant and the concentrations of the reactants
The Reaction Rate
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
