4. Comment how the concentration affects the rate.a. Concentration definitely has an affect on the rate. When there is an increase inconcentration, the rate as which the reaction occurs also increases. This is provedthrough my data. As concentration of oxalic acid increases, here are my rates thatgo from lowest concentration to highest concentration: 3*10$ M/s, 6.8*10 M/s,9.26*10 M/s, 1.15*104 M/s. Here, as the number of molecules in a given volumeare increased (due to concentration increase) the number of effective collisionsalso increase. This causes the increase in reaction rate. Comment how the temperature affects the rate.a. Temperature definitely has an affect on the rate. When there is an increase intemperature, the rate at which the reaction occurs also increases. This is provedthrough my data. As each experiment had an increasing temperature, here are myrates that go from lowest to highest temperature: 3.25*10 M/s, 4.15*10 M/s,6.85*10 M/s, 9.17*10* M/s. With this increase in temperature, there is thereforean increase in the energy of molecules in the solution. With this increase inenergy, there is an increase in collisions with enough energy, and this ultimatelyleads to the rate increasing.

When there is an increase in concentration, the rate as which the reaction occurs also increases. This is proved through my data. As concentration of oxalic acid increases, here are my rates that go from lowest concentration to highest concentration: 3*103 M/s, 6.8*10³ M/s, 9.26*10* M/s, 1.15*10“ M/s. Here, as the number of molecules in a given volume are increased (due to concentration increase) the number of effective collisions also increase. This causes the increase in reaction rate.
