Rate of reaction essay


rate of reaction essay

is high only a small amount of particles will have enough energy to react so the reaction rate would be very small, however, if the activation energy is very low the number of particles with that amount of energy will. It is needed to break existing bonds this process is called endothermic. The energy used by colliding particles is called Activation energy. This graph shows that there is an increase in the rate of reaction as the temperature increases. 1/2 mv.

Also our results were not accurate but this could be because of a number of reasons. In the endothermic reaction H. The effect of temperature on rates of reaction. A change in concentration is a change in the number of particles in a given volume.

I also cut out some temperatures where the time taken for the black cross to be obscured was similar to other temperatures. 2) Increases the average amount of energy particles have so more particles have the activation energy, both of these changes make the rate of reaction go up so we see a decrease in the amount of time taken for the reaction and an increase. Apparatus This is the apparatus we used to measure the amount of H2 that was produced in the reactions. To the nearest.01 of a gram.01. But the mass of the particles remains constant so we can eliminate that part of the equation so; V2T, therefore we can fit this into a formula: V21/V22 T1/T2, if we substitute the temperature into the formula we can work out the average speed. Because the reaction reacts one mole of magnesium to two moles of hydrochloric acid we have to make sure that even with the lowest concentration of acid we still have an excess of acid. 100.2 75 25.1 25 75.05 The reason why we used.01g of magnesium was because it was therefore easy to measure because there was not too much, or too little. If you double the concentration of the acid the reaction rate would also double, this is because there are more particles in the solution which would increase the likelihood that they would hit the magnesium so the reaction rate would increase. The only thing I will be changing for each reaction will be the temperature. This will therefore cause them to move faster and produce more successful collisions, causing the rate to increase.
