There are fewer reactants left to collide.
The concentration of the reactants decreases.
In general, and depending on the order of the reaction, the rate will decrease as the reaction progresses.
During neutralization, an acid and a base react to form water and a salt. This reaction is usually exothermic, releasing heat and causing the temperature to increase. As the reaction progresses and reaches completion, the temperature may then decrease as the system returns to equilibrium.
The concentration of the reactants decreases.
The relationship between potential energy and reaction progress is that potential energy changes as a reaction progresses. At the beginning of a reaction, potential energy is high as reactants are being converted into products. As the reaction progresses, potential energy decreases until it reaches a minimum at the point of maximum stability, known as the transition state.
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 reactant concentrations decrease
A first-order reaction will never be completed because the reaction rate depends only on the concentration of one reactant. As the reaction progresses and the reactant is consumed, the concentration of the reactant decreases, causing the reaction rate to also decrease. This gradual decrease in reaction rate means that the reaction will continue indefinitely, given enough time.

RATE OF REACTION / REACTION RATE definition? don't go to wikipedia...
The concentration of the reactants decreases.
The rate decreases as reactants are used up.
The relationship between potential energy and reaction progress is that potential energy changes as a reaction progresses. At the beginning of a reaction, potential energy is high as reactants are being converted into products. As the reaction progresses, potential energy decreases until it reaches a minimum at the point of maximum stability, known as the transition state.
decrease
Enzymes decrease the activation energy of a chemical reaction. They do this by providing an alternative pathway with a lower activation energy that allows the reaction to proceed more rapidly.
The rate of a reaction begins to decreases as reactant are used up
