A chemical reaction is the change of a molecule from one arrangement to another. Our whole bodies are made up of cells, which are chemical systems. To sustain life there must be chemical reactions all throughout the body (Barnhart and Hopper 2011). At what rate the reaction can occur is dependent on the activation energy. Activation energy is the amount of energy the reactant molecules must surpass for the reaction to occur (Mathew Bui et al. 2006). Temperature and catalysts are the most basic ways to overcome activation energy (Barnhart and Hopper 2011). They help provide the reaction with the extra push it needs to get the reaction going.
More specifically temperature deals with the kinetic energy form heat, the more reactant molecules that rise over the activation energy level the faster the reaction occurs. Catalysts lower the activation energy level allowing the reaction to occur more rapidly (Barnhart and Hopper 2011). Most catalyzes are also known as enzymes (Barnhart and Hopper 2011). Enzymes are designed to only be able to …show more content…
My hypothesis was supported because the cuvette at 37°C had a higher reaction rate than both cuvettes at 4°C and 22°C. This was the case due to the energy activation level. The higher temperature allowed for more kinetic energy within the cuvette. The initial breaking of bonds is due to activation energy (Cox). When particles collide gently, there is not enough energy for the reaction to occur (Cox). The amount of kinetic energy in the collision of particles depends on the activation energy, causing frequency and speed to vary (Cox). The enzyme allowed for a catalyst of all of the cuvettes but the heat allowed for the notable acceleration in the higher temperature
