Final answer:
In a chemical reaction, adding heat increases the reaction rate. Stirring the reaction helps distribute heat evenly. The reaction is considered done after stirring for 30 minutes.
Step-by-step explanation:
In a chemical reaction, adding heat can increase the reaction rate. In a chemical reaction, adding heat increases the reaction rate. Stirring the reaction helps distribute heat evenly. The reaction is considered done after stirring for 30 minutes.
When heat is added, the molecules move faster, increasing the chance of collisions between reactant particles and leading to a faster reaction. Stirring the reaction helps to evenly distribute the heat and maintain a consistent temperature throughout the reaction mixture. By letting the reaction stir for 30 minutes, it allows enough time for the reactants to fully react and reach equilibrium. At this point, the reaction is considered done.
