For endothermic reactions the increase in temperature increases the K.E of the molecules and numbers of effective collisions per unit volume per unit time among reacting molecules becomes increased so rate of the reaction also becomes increased.
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
The Hotter the temperature, the faster the particle moves. During the reaction, atoms transfer in different molecules (or compounds), therefore the temperature does affect the speed of the reaction.
Temperature is a fact for speed. Speed is increasing with the temperature.
Factors that can slow down an enzyme reaction include low substrate concentration, low pH levels, high temperature, or the presence of inhibitors. Conversely, factors that can speed up an enzyme reaction include high substrate concentration, optimal pH levels, optimal temperature, or the presence of activators.
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... :)

3 factors that affect the speed of an enzyme catalysed reaction are: .Temperature .Enzyme Concentartion .Substrate concentration
Higher temperatures result in faster reactions.

Temperature can change the speed of some reactions.
