What describes a reaction that reaches equilibrium?
The product and reactants reach a final, unchanging level.
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.
How will decreasing reactant concentration affect the reaction rate?
Decreasing the reactant concentration will slow the rate of the reaction. If you use the idea of adding oxygen and hydrogen to make water and decease the amount of one, you will produce less water. It doesn't matter which reactant is less as there are just are not enough to go around.
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
True or False chemical reaction occurs at the same rate no matter what size of the reactant particles?
False! Not all chemical reactions take place at the same rate.
What is the connection between temperature collisions and reaction rate?
More collisions between particles of matter means a faster reaction rate. When you increase the kinetic energy of a sample of matter, you increase the number of particle collisions, as well as the force with which they collide. This in turn increase the rate of reaction.
How reaction rate is useful in real life?
its not.
What measures of how fast reaction occurs?
The measure is the rate of reaction.
What is the speed at which a reaction occurs called?
The chemical term is reaction 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
True or False chemical reaction occurs at the same rate no matter what size of the reactant particles?
False! Not all chemical reactions take place at the same rate.
What are three reasons why enzymes are important?
Enzymes are biological catalysts. They allow the reaction to occur, basically putting together molecules to allow the reaction to happen. They increase the rate of reaction without changing the outcome of the reaction. Increasing the rate of reaction so these reactions can occur fast enough to support life.
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.
