The rate of a reaction is the time it takes for a reaction to take place. The rate of reactions can be affect by different factors such as the temperature, the air pressure, the concentration of each substance and whether a catalyst is used (a catalyst is something that lowers something's activation energy so the reactants have more energy to react). A reaction happens when atoms collide with each with a big enough force therefore a bigger surface area would help speed this up. Also the amount of energy the particle/atoms have helps. With these factors you can determine the speed at which a reation happens. Any questions?

exploding dynamite
What special proteins speed up the rate of condensation and hydrolysis reactions?
Enzymes are special proteins that speed up the rate of condensation and hydrolysis reactions by lowering the activation energy required for these reactions to occur. They act as biological catalysts to facilitate these biochemical reactions in living organisms.
How does the rate of endothermic reactions change as temperature is increased?
As temperature increases, the rate of endothermic reactions also increases. This is because higher temperatures provide more energy for the reaction to occur, leading to a faster reaction rate.
How are rate constants temperature dependent in chemical reactions?
Rate constants in chemical reactions are temperature dependent because as temperature increases, the molecules move faster and collide more frequently, leading to a higher likelihood of successful reactions. This relationship is described by the Arrhenius equation, which shows that rate constants increase exponentially with temperature.
Equilibrium is achieved when the and chemical reactions continue to take place at the same rate?
Equilibrium is achieved when the rate of the forward reaction equals the rate of the reverse reaction, resulting in no net change in the concentrations of reactants and products. At equilibrium, chemical reactions continue to take place, but the overall concentrations of reactants and products remain constant.
Is speed the rate of change?
NO! It is the rate of reactions!
How particle collisions that affect the rate of chemical reactions?
When the number of particle collisions increase the rate of chemical reactions also increase.
What has the largest rate constant k?
exploding dynamite
Do enzymes decrease the rate of chemical reactions?
No, they Increase the speed of chemical reactions
What are the 5 factors that can affect the rate of chemical reactions?
5 factors that can affect the rate of chemical reactions are temperature, pressure, concentration, stirring, catalysts.
How the difference in the movement of atoms at two different temperatures affects the rate of most chemical reactions?
Generally at high temperature the rate of chemical reactions is greater.
What effects does the concentration of reactions have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
If the temperature is increased the rate of most reactions will?
The rate of most will also increase.
What is rate reactions?
Rate of reation is the time taken for a reaction to take place and the smell it has
Substance that increases rate of chemical reactions?
catalyst
How does the rate of a reactions change after a catalyst is added?
Nose
How do enzymes regulate the rate of reactions?
Enzymes serve to speed up reactions by lowering the energy of activation
