The solution becomes increasingly difficult to see through as more and more sulphur is formed. WHAT IS RATE OF REACTION? The rate of reaction tells us how quickly a chemical reaction happens. Rate is measuring of the change that happens in a single unit of time. Cause its not enough to know if a reaction is fast or slow. We can't work out the rate of reaction from its chemical equation. Equations can only tell us how much product we can get. They don't say how quickly it is made. We can only find the rate by actually doing experiments. During a reaction, we...
