Research question: How can different temperatures affect the rate of reaction, when the reactant is in powder form?
Hypothesis: If the temperature of the water is increased, the rate of reaction will also increase as the heat given off to the particles will increase leading to more movement and frequent collisions.
Background information: Chemical reactions occur when two or more molecules interact with each other, but that can only occur when they interact at a specific geometrical orientation and when the activation energy needed for the reaction is exceeded. The reactions can either be endothermic, with heat being absorbed from the surroundings to the system, or endothermic, with heat given …show more content…
It is used for mild to moderate pain such as headaches, migraines, or for lowering a high temperature or relieving aches or discomfort associated with colds and flu. Panadol contains around 500 grams of Paracetamol, which is a mild and safe pain reliever. Due to its composition of Paracetamol, the pain is relieved because the paracetamol reduces the production of prostaglandins in the brain and spinal cord. Prostaglandins are produced when injury or certain diseases affect the body, and so they give off warning to the brain by stimulating …show more content…
But due to the heavy attraction from the water molecules, the bonds in the Panadol molecule are broken down and carried away with the oxygen molecule, resulting in dissolving. As the oxygen molecules have enough energy or attraction to separate the molecules within the original Panadol molecule.
Rate of reaction can be described as a measure of the speed at which a chemical reaction occurs, where many factors can contribute in either increasing or decreasing the speed. Temperature can be seen as one of the factors that contribute in the effect, alongside with reactant concentration, surface area and catalysts. Temperature is the amount or intensity of heat present in a substance or object. Rate of reaction and temperature are linked due to their knock on effect. Where an increase in temperature of the solute (water) will lead to an increase in the rate of reaction between the water and the powder
