Studying doesn’t have to feel like a slog. The truth is: your brain isn’t built to drag through hours of tedium—it responds best to pattern, reward and rhythm. By shifting how you approach study time, you can turn it from duty into something your brain actually enjoys. Here are five simple, smart ways to do it. Try one today and see how your focus follows. 1. Study in Short Bursts, Not Endless Sessions Forget the idea that you must sit for three hours straight. Cognitive science shows our attention drops significantly after about 25–30 minutes. So use the Pomodoro Technique : study for 25 minutes, take a 5‑minute break; after four rounds, give yourself a longer break (15–20 minutes). That rhythm gives your brain permission to reset—and makes that “next block” easier to start. 2. Turn Learning into a Game The brain loves victory—even tiny ones. Set fun micro‑challenges: finish chapter one in 20 minutes, get 10 questions right in a row, or beat yesterday’s time. E...
The rate of a chemical reaction is the number of moles of reactants converted or products formed per unit time. It varies from one chemical reaction to another because some chemical reactions are faster than others. The rate at which a reaction occurs and its control are significant in industries because they are the factors that determine if the reaction will make economic sense or not. How to measure the rate of chemical reaction Consider a reaction between irons and dilute hydrochloric acid Fe (s) + 2HCl (aq) → FeCl 2(aq) + H 2(g) As the reaction proceeds, the iron is used up and iron (II) chloride and hydrogen gas are formed. The rate of the chemical reaction between iron and the acid can be determined by: · Taking a given mass of iron · Adding an excess of hydrochloric acid · Noting the time taken for a...
