The rate of a chemical reaction can be increased by using smaller solid particles which increases the surface area of a solid reactant. This is done by cutting the substance into small pieces ...

JON CHASE:Decreasing the size of the particle increases the rate of reaction and that's because we have increased the surface area. JON CHASE:'So let's recap. 'To increase the rate of a reaction ...

Photocatalysis—a chemical reaction driven by light in the presence of a photocatalyst—is poised to play a key role in next-generation technologies, including hydrogen production through water ...

More dissolved particles leads to more collisions and a faster reaction. In your trials, when was the surface area the largest? Did the rate go faster? Temperature also affects the rate of a reaction.
