All chemical reactions must be thought of as collisions between the particles of reactants and products. As the temperature of the reaction increases, the energy of the particles also increases and so there is a greater chance of more collisions occuring, and as a result, in general, an increase in reaction temperature increases the reaction rate

An increase in temperature will cause the rate of a chemical reaction to?
Increasing the temperature the dissolving rate increase.
Increased temperature usually leads to an increase in reaction rate because collisions are?
The increase in reaction rate is due to an increase in the number of collisions. This is because an increase of temperature causes an increase in molecular motion.
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.
Why does grinding a solid into powder increase reaction rate?
Increased surface area for reaction to occur on
What causes the reaction rate to decrease as the reaction progresses?
The concentration of the reactants decreases.
An increase in temperature will cause the rate of a chemical reaction to?
Increasing the temperature the dissolving rate increase.
How do you enhance rate of reaction in CSTR?
rate of a reaction can be increased by increasing the temperature if the reactor

What happens to the rate of enzyme concentration when you increase substrate concentration?
The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant.
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.

What causes the reaction rate to decreases as the reaction progresses?
The concentration of the reactants decreases.
Why does the reaction of hydrogen and oxygen gas excel in the presence of a flame?
The rate of this reaction is increased at high temperature.
What causes you to breathe rapidly after running?
Increased Heart Rate
What do concentration surface area and temperature have in common?
They can all affect the rate of a chemical reaction.
