RATE OF REACTION / REACTION RATE definition? don't go to wikipedia...
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
the rate decreases
As the temperature increases, the reaction time decreases.
It will increase the rate of the reaction because more particles will be exposed and they will be able to react.This decreases the time to react.
The concentration of the reactants decreases.
The rate decreases as reactants are used up.
The concentration of the reactants decreases.
In general, and depending on the order of the reaction, the rate will decrease as the reaction progresses.
The reaction rate depends on the order of the reaction. In general (except for zero order), as the reaction progresses, the rate decreases with time.

An inhibitor decreases the reaction rate
Inhibitor

The rate of a reaction begins to decreases as reactant are used up
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.
