As the rate is changing throughout the reaction, we are calculating the average rate over a given time period. For example, the graph below could be used to calculate the average rate over any ...

We can use a gas syringe to measure the reaction of metals with dilute acid. When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas. We can measure the rate of the ...

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 ...
