Which statement about reaction rates is true? changing the amount of reactants will not change the reaction rate. changing the temperature cannot speed up a reaction rate. changing the surface area affects the reaction rate. a catalyst slows down the reaction rate.

you can have just about every answer you can think of

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
