INTRODUCTION
Rate of reactions play a vital role in real life situations. Everyday situations, such as cooking, require reaction rates to be increased. To bake some cookies, you place them inside an oven. But why is that? Well, placing the cookies in the oven speeds up the rate of the reaction by heating it up. When the cookies have more heat energy, they cook faster. Additives may be added to foods to speed up the reaction. These are called catalysts. Likewise, we place milk in our fridges to slow down the reaction rate by removing heat and preventing the milk from going bad. This is because the milk would turn sour if we left it out near a window. (14)
Enzymes are used to speed up biological reactions. When digesting food, enzymes are used as biological catalysts to speed up metabolisms. Excess heat from this is used to regulate the temperature of endothermic animals’ bodies. When a person is ill, their body temperature increases as heat fights bacteria by slowing down the rate of bacteria production. Respiration is another example of when reactions are sped up in biological systems. Rates of reactions
