Answer :
Final answer:
Sulfuric acid acts as a dehydrating agent by removing water from substances, increasing particle collision and energy accelerates a chemical reaction, and the average rate of a reaction can be calculated using given data.
Explanation:
Sulfuric acid acts as a dehydrating agent by removing water from other substances. Its strong affinity for water enables the acid to extract water molecules from compounds, creating carbon, heat, and steam as byproducts.
Increasing the chances of particle collision and increasing the energy of the particles colliding with each other can accelerate the rate of a chemical reaction by promoting successful collisions with sufficient energy.
If 80 cm³ of gas was given off in a reaction in 20 seconds, the average rate of reaction would be 4 cm³/s. Rate of reaction is calculated as the change in amount of reactants or products over time.
