A Pyrotechician is working on a new fourth of July rocket. He is using a highly reactive metal when burned. What can he use to lower the reaction rate????
larger particles, separate the particles with a filler (expanded clay?).
What things influence the rate of reaction?
Temperature influences the reaction rate i think
yes, you can lower the temperature...but with fireworks that is difficult.
Particle size is another factor.
Closeness is another factor.
To lower the reaction rate of the highly reactive metal used in the fourth of July rocket, the Pyrotechnician can employ a few strategies. One common method is to use an oxidizer with a lower reactivity, which will slow down the overall reaction. Another approach is to mix the highly reactive metal with inert materials, such as sand, clay, or graphite, which act as diluents to reduce the concentration of the reactive metal. This decreases the likelihood of rapid and violent reactions.
Additionally, the Pyrotechnician can control the reaction rate by adjusting the particle size of the highly reactive metal. Smaller particles generally have larger surface areas, allowing for more extensive contact with the oxidizer and increasing the reaction rate. On the other hand, larger particles have reduced surface areas, leading to slower reactions.
The Pyrotechnician can also modify the temperature at which the reaction takes place. By lowering the temperature, the energy available for the reaction decreases, resulting in a slower reaction rate.
It is crucial for the Pyrotechnician to carefully evaluate and test these modifications to ensure the desired reaction rate is achieved while maintaining the necessary properties for an effective rocket.
