Explain using particle theory the affect of increasing

Explain, using particle theory, the affect of increasing the temperature of a reaction. Particles have more energy • Particles collide more • More of the collisions are successful because have the activation energy • Particles move faster • Ignore: particles move more, collide quicker, more collisions, increases particle activation energy.

Explain, using particle theory, the affect of increasing the concentration of reactant on the reaction More reactant particles in the same volume. • • More collisions. Ignore: more energy, bigger surface area, particles are moving faster

Explain, using particle theory, the affect of increasing the pressure of a • Same number of reaction. reactant particles in a smaller volume. • Particles are closer together. • More collisions. Ignore: more energy, bigger surface area, particles are moving faster, more particles.

Explain, using particle theory, the affect of using powdered reactant in the reaction. • Increases the surface area. More reactant particles are exposed to the other reactant. • • More collisions. Ignore: more energy, particles are moving faster, more product produced.

Explain how a catalyst affects the rate of reaction. • Lowers the activation energy • More successful collisions • Important in industry to reduce costs • Never used up • Increases the rate of reaction Ignore: gives particles more energy.
