The concentration of the reactants decreases.
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.
There are fewer reactants left to collide.
The rate of a reaction begins to decreases as reactant are used up

RATE OF REACTION / REACTION RATE definition? don't go to wikipedia...
An inhibitor decreases the reaction rate
Inhibitor
A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does so by providing an alternative reaction pathway that requires less energy to initiate the reaction. The catalyst itself remains unchanged at the end of the reaction and can be used over and over again.
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.
The how much speed it takes for two substances to make one product. Many factors can affect this including the temperature, the surface area, the concentration, the catalyst and the pressure (only applies for gases)
