Does changing the concentration affect the rate of osmosis?

Yes. The rate of osmosis is determined by several factors, including heat, molecule size, and concentration gradient. The concentration gradient is essentially the difference between the concentration within part of the system to that concentration in the rest of the system. So, the hotter the water (solution)/the smaller the molecules/the greater the concentration difference, the greater (faster) the rate of osmosis.
