HELP!! ill fan and medal!!!! Explain how an increase temperature affects reaction rates. Use the following terms in your explanation: kinetic energy of particles, frequency of collisions, and rate of reaction.

    Increase in temperature (generally) increases the rate of your reaction; in certain cases if you have a reversible reaction, an increase in temp may cause your equilibrium to shift from products to reactants. However temperature is defined as the average kinetic energy of the particles, KINETIC, because that means that the particles are in motion. As you increase the temperature the avg kinetic energy increases of the particles, and that increases the frequency of your collisions, and also the probability that your particles will collide. Also there are two things to consider: you need to break bonds and form bonds in a chemical reaction. the former, breaking bonds, implies putting in a certain amount of energy Ea activation energy, and when you increase your temperature what your doing is that your increasing the chance that your particles will collide with the proper orientation as well as your reaction rate.

    All reactions whether they are exo or endothermic have a minimum energy requirement Ea that must be satisfied in-order for the reaction to get going.

    so how would i sum this up into like a sentience or two?

    As you increase your temperature, the average kinetic energy goes up, and hence the frequency of the collisions of particles goes up as well. This effect overall increases your rate of reaction.

    the higher the temp the faster reaction

    Long story short.. that's really the definition of temperature. yeah sure
