For example, Respiration – we inhale oxygen which reacts with glucose and produces carbon dioxide, water and energy. The reaction is given below. C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy.
WebApr 11, 2024 · The concentration of the chemical reactants also affects the rate of reaction by altering the number of reacting molecules. A higher concentration increases the number of molecules available for collision. This increases the rate of collision and hence the rate of reaction. Reducing the concentration, therefore, reduces the reaction rate. WebThis is an example of an endothermic reaction. In Julie’s case, when calcium chloride was dissolved in water, the system released heat into the surroundings, the flask, and thus the flask felt hot.
