Temperature (rate increases with temp increase)
Pressure (rate again increases with press increase)
Concentration (rate increases with concentration increase)

It is true that cold usually speeds up reaction rates?
No, low temperatures usually slow down reaction rates.
Which statement best describes the use of a catalyst in a fuel cell?
It increases reaction rates
When a reaction system is at equilibrium the rates of the reaction in the forward and reverse directions are?
Equal to one another. K= k1/k-1 where k1 is the forward reaction, k-1 is the backwards reaction and K is the equilibrium constant.
Describe the factors which affect chemical reaction rates?
The factors that change the reaction rates of chemical reactions are: 1)temperature 2)concentration 3)pressure 4)physical state 5)a catalyst
Which of these factors will not affect reaction rates?
The proper term for the phenomenon of reaction rates is known as chemical kinetics. Generally for any chemical reaction factors such as temperature, concentration, pressure, physical state, presence of a catalyst, and the reaction rate order. Reaction rate order is specific for each chemical reaction. So to sum it all up, if you influence the environment in a manner that does not change one of these listed variables, then it will not likely do anything to a reaction rate. But to be honest, I can't think of a single thing you could do to a reaction that wouldn't influence one or more of these parameters.
What will not affect reaction rates?
Astrological signs will not affect reaction rates.
How does physical states relate to reaction rates?
The reaction rates are higher in gases.
How nuclear decay rates different from chemical reaction rates?
nuclear decay rates take more time and chemical reaction rates could happen fast.
What are some factors that affect human reaction rates?
There are a number of factors that affect human reaction rates. Temperature is one major factor that affects human reaction rates for example.
Which of the following statements is true Chemical reaction rates vary with the conditions of the change but nuclear rates do not Nuclear decay rates vary with the condition?
"Chemical reaction rates vary with the conditions of the change but nuclear rates do not."
What reaction is the speed with which reactant turn into products?
You think probable to the reaction rate of a chemical reaction.
How many reaction rates be measured?
8
How are reaction rates used in medicine?
yes.
What is a protein that affects reaction rates?
These are called enzymes.
What causes the concentration of reaction to affect the reaction rates?
It increases the number of collisions at the right orientation.
It is true that cold usually speeds up reaction rates?
No, low temperatures usually slow down reaction rates.
What are the main factors that effect reaction rates?
Affinity and temperature.
