Question:

How does temperature affect reaction rate?

Answer:

As temperature increases, the movement of atoms and molecules increases which allows for these molecules to collide at a higher rate. As the collision rate increases, the reaction rate increases.

Question:

Explain the processes of diffusion, osmosis, and active transport and how they are different.

Answer:

Diffusion is the passive movement of particles along a concentration gradient, from a high to low concentration area. Osmosis is a type of diffusion that also uses passive movement but it specifically pertains to the movement of water molecules through a semi permeable membrane (water moves from an area of low solute concentration to a high solute concentration). On the other hand, active transport requires energy for particles to move. Similarly to diffusion, active transport moves particles from low concentration areas to high concentration areas.
