on Theory. This is a theory that is used to predict the rate of a reaction. The Collision Theory is based on the idea that for a chemical reaction to take place, it is necessary for the reacting particles to collide with each other with enough energy to break or form new bonds between the other particles, which is called a successful collision. If when they collide and they do not have enough energy to break or form new bonds then they will simple bounce of each other, causing an unsuccessful collision.
Ways that I could record my experiment
There are several way which I could record my experiment. The possible ways are as follows:
I could use a gas syringe to collect the gas that will evolve from my experiment. I could use these results to calculate the initial rate of reaction.
The weight before and after the experiment
I could put the conical flask with the chosen volume of hydrochloric acid onto a set of accurate electronic scales and record the weight of it. I could then drop a piece of magnesium into the conical flask and measure the decrease in weight at chosen intervals. The weight of the experiment will decrease because as the hydrogen in the hydrochloric acid is being displaced it is being released and will float up and out the conical flask, the weight change will not be very big, but there will be one.
How long the magnesium takes to dissolve
I could measure the length of time it takes for the magnesium to dissolve. The only problem with recording my experiment this way is that I could only calculate the average rate of reaction and not the initial rate of reaction
Ways to measure the rate of the reaction:
I will be using the initial rate to calculate the rate of reaction as it can calculate the true rate and not the average rate of reaction.
The factors that could affect the rate of reaction of my experiment are as follows:
This could affect the rate of reaction because the higher the concentration of...
