Connect each of these circumstances to the rate of a reaction. Explain how the change in circumstances could be implemented in a lab and describe the predicted outcome: 1. Increased temperatur
2. Decreased solution concentration
3. Increased surface area of a solid
4. Increasing the rate the reaction without being involved in the reaction.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

Blank allows you to do calculations for situations in which only the amount of gas is constant a)boyle's law b)combined gas law c)ideal gas law d)dalton's law
