How does a change in temperature from 25o to 50o affect the rate of the reaction rate?
The general rule of thumb is that the reaction rate will double for each 10ºC change in temperature. So, going from 25 to 50 degrees, would increase the reaction rate APPROXIMATELY by 4.5 times. This is not a law, but just a general rule of thumb for approximating the rate.
Are atoms more attracted to each other when you raise or lower the temperature?
The reaction rate is higher when the temperature increase.
How many reaction rates be measured?
The reaction rate can typically be measured by determining the change in concentration of reactants or products over a certain time period. Depending on the specific reaction and conditions, it is possible to measure multiple reaction rates simultaneously, involving different reactants or products. Each reaction rate will depend on factors such as concentration, temperature, pressure, and catalyst presence.
Will increasing the temperature cause an increase in the rate of a reaction?
increased temperture causes rate or reaction to increase.
What causes a reaction in particles?
Particles can react with each other when they collide and exchange energy or change their arrangement of atoms. The nature of the reaction is often determined by the types of particles involved, their energy levels, and the conditions of the environment. Various factors, such as temperature, pressure, and concentration of particles, can influence the likelihood and outcome of reactions.

Does the change of temperature will slow or faster the chemical reaction?
No, an increase in temperature will speed up the reaction. This is because the heat energy is transferred into kinetic energy (movement energy) in the reactors and this increases their speed and so increases the rate at which they collide with each other, increasing the rate of the chemical reaction.
Are atoms more attracted to each other when you raise or lower the temperature?
The reaction rate is higher when the temperature increase.
What is meant by fair testing?
A fair test is one in which all the conditions of every sample are kept the same, except the one variable which is being studied. For example, if you were testing the effect of temperature on the speed of a reaction, you would change only the temperature, keeping the pressure of the reaction, the amount of each chemical used etc. the same.

What information do you need to determine how a change in pressure will affect the equilibrium of a reaction?
The total number of moles of gas on each side of the reaction.
What happens to the total number of atoms of each element before and a after a chemical reaction?
It does not change
Will increasing the temperature cause an increase in the rate of a reaction?
increased temperture causes rate or reaction to increase.
How each mode of heat transfer varies with change in temperature?
Fred
A submarine changed its depth by -24 feet each for 6 minutes. What was the total change in depth at the end of the 6 minutes?
The total change in depth is -144 feet.
Liquid alcohol will change to vapor when its temperature reaches the what?
Liquid alcohol will change to vapor when its temperature reaches its boiling temperature. When alcohol reaches its boiling temperature, each molecule of alcohol has enough energy to separate from each other, so each molecule can move freely. The boiling point of liquid alcohol is 351K or 78C
Is the rate of a chemical reaction dependent of temperature?
In general, as temperature rises, so does reaction rate. This is because the rate of reaction is dependent on the collision of the reacting molecules or atoms. As temperature rises, molecules or atoms respond with increased motion, increasing the collision rate, thus increasing the reaction rate.
