Which of these statements is true according to the solubility curve graph ? a.) More KNO3 will dissolve than KBr at 0 degrees Celsius.
b.)Temperature has little effect on the water solubility of NaCl.
c.)KBr is insoluble in water at low temperatures.
d.) An increase in temperature causes a decrease in the solubility of NaClO3 in water.

a is the answer to the question

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
