According to collision theory, which of the following statements explain why an increase in temperature increases the rate of a chemical reaction? (Select all that apply.)

The reactant particles have a greater average kinetic energy.

A smaller fraction of the reactant particles have energy greater than the Ea.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
