What else can I help you with?
Why does increasing the temperature of a reaction increase its rate?
It provides energy to overcome the activation energy.
Can increasing temperature increase the number of protons?
No - except in extremes and as part of nuclear processes.
How does a temperature increase cause the rate of a reaction to increase increase?
It increases the kinetic energy of the molecules (APEX)
Gas pressure is affected by?
Gas pressure is affected by factors such as temperature, volume, and the number of gas molecules present. Increasing the temperature or decreasing the volume of a gas will result in an increase in pressure, while increasing the number of gas molecules will also increase the pressure.
What effect does raising the temperature have on the speed of reaction for the forward reaction and why?
In general, but not always, increasing the temperature will increase the rate of the forward reaction. This is because an increase in temperature increases the speed at which the molecules move, increasing the kinetic energy, and thus making it easier to reach the activation energy. Of course, this is true only for endothermic reactions. If the reaction is exothermic, then increasing the temperature will slow down the forward reaction.
What happens to the temperature increase the number of particles what happens to the pressure?
Increasing the temperature the number of particles remain constant and the pressure increase.

What the increasing temperature doas to the particles and how this affects the number of collisions?
Increase in temperature cause the particles to move faster, which in turn would increase the number of collisions. If the volume did not change and the temperature increased, the pressure would also increase.

What does increasing the number of molecules in a fixed volume result in?
Increasing the number of molecules in a fixed volume will result in an increase in pressure due to more frequent collisions between molecules. This relationship is described by the ideal gas law, where pressure is directly proportional to the number of molecules and temperature, and inversely proportional to volume.
How does pressure temperature and the number of particles affect the behavior of a gas?
The combined gas equation is used to calculate the behaviour of gas under different temperature, pressure and number of particles. PV = nRT Where P is pressure V is volume n is the number of moles T is the temperature in Kelvin and R is the Ideal Gas Constant. If P is in kPa and V is in dm3 then R = 8.31.
What would cause the pressure of a gas to increase?
An increase in temperature or a decrease in volume would call the pressure to increase. Apex- increasing the number of gas particles
How particle collisions that affect the rate of chemical reactions?
When the number of particle collisions increase the rate of chemical reactions also increase.
How does temperature affect enymatic activity?
Heat will increase the rate of any chemical reaction. This is because a chemical reaction require three things: The molecules to collide, collide with enough energy, and collide in the correct orientation. With increased heat you increase the number of collision and the energy with which molecules collide. For non-organic enzymatic reactions(ex platinum catalyzes several hydrogen reaction) heat will speed up the reaction. For organic reactions heat will only increase the rate up to a point. If the temperature gets too hot it begins to denature the enzyme and the enzyme will no longer work.
