Chemical reactions depend on the interaction of atoms and molecules with each other. Any change which will alter the frequency of such interactions occurring will alter the speed of the reaction. Temperature will affect the speed of a reaction, as will stirring or agitating the reagents together. The chemicals must also have enough energy available to reach the activation energy of the desired reaction in order to form the product. Catalysts are chemicals that speed up reaction time by lowering the activation energy without being consumed in the reaction themselves.

What things might slow down or speed up and enzyme reaction?
The temperature in addition to the pH sacle of something in particular in the environment would affect the rate of speed of an enzyme and would slow down the reaction if it is too high.
What are things that can affect the speed of a chemical reaction?
Some different things that could speed/slow up/down a chemical reaction are: Temperature (If higher, molecules move faster, reactions speeds up) SPEED UP Temperature (If lower, molecules will move slower, reaction slower) SLOW DOWN CATALYST (A catalyst is anything that SPEEDS up a reaction without being consumed[running out of energy]) SPEED UP Concentration More substrates [reactants/puzzle pieces to enzymes faster reaction)SPEED UP Concentration (Less substrates- slower reaction) SLOW DOWN ...well, there you go... :)
How does temperature affects the rate of industrial reaction?
It depends. A higher temperature will speed up an endothermic reaction, but slow down an exothermic reaction.
Does alcohol speed up reaction time and promotes good judment?
No, alcohol does not speed up reaction time, alcohol infact INCREASES SPEED of reaction time, thus SLOWING DOWN reactions. Alcohol doesnt promote good judgement, it impares it due to the slow down in activity of the neurones in the brain.
Does adding water slow down a chemical reaction?
Adding water can often slow down a chemical reaction by diluting it. This is the case of a quantitative reaction such as an enzymatic reaction.
What things will slow down or speed up a chemical reaction such as between vinegar and baking powder?
Heat would speed up the reaction, while cold would slow the reaction.

What can you put in milk to slow down the speed of souring?
You dont put in anything to slow it down, you simply reduce the temperature thus causing the reaction to slow down

Will a smaller surface speed up a chemical reaction?
No. A smaller surface area will slow down a chemical reaction.

What is true about enymesQ1 they slow down reactionsQ2 they speed up or slow down any reaction in a living thingQ3 they act as catalysQ4 they only speed up reactions?
They act as a catalyst in that they lower the activation energy.
Why do Slow down and slow up mean the same?
I think you mean slow down and speed up. slow down =slow, speed up=fast
Can a catalyst be used in place of an inhibitor?
umm no. they are opposites. a catalyst will speed up a reaction and an inhibitor will slow it down.
