Why do reactions generally occur faster at high temperatures based on the collision theory? Choose all that apply High temperatures mean: - lower the activation energy requirement - high kinetic energy= greater number of collisions per time unit - increase solubility - high internal energy= more effective collisions by energy levels (activation energy)

5. The collision theory of reaction rates states that the rate of a reaction depends on the number of collisions between mol- ecules, the average energy of the collisions, and the effectiveness of the collisions. (a) How does temperature affect each of these factors in collision theory? (b) Does the effect of temperature on the reaction rate support the collision theory of reaction rates? Explain.
Explain the difference in reaction time between the powder and chunk forms of calcium carbonate using principles of collision theory
16. How can the effect of temperature on the reaction rate be explained by collision theory?
According to collision theory, the increase observed in the rate constant with increasing temperature is at least partly attributed to the fact that the enthalpy change for most reactions is negative. True or False.
