Answer C By increasing the surface area of the solute Explanation The rate of reaction means how much time is taken for the reaction to happenThe rate of the reaction depends on the surface area of solute When we crush a cube of solute, the surface area increases as more surface of the cube can interact with the solvent and thus the rate of dissolution will increase...
