Question

a. Find out the relation between Temperature and rate of a reaction? Select the materials from the list above Sodium the Sulphate, Test tube, dil HCl, Cu, Mg ribbon, Beaker, Water, Spirit lamp, boding Tube 

b. Prepare a write up for finding the relation between temperature and rate of a reaction? 

c. Why rate of a reaction increase when temperature increases?

Answer 1

a. Essential Materials:- 

Sodium Thiosuphate, Hydrochloric Acid, Water, Boiling Tube, Spirit Lamp. Prepare a solution of diluted sodium Thiosulphate in a beaker. Take equal amount of this solution in two Boiling Tubes. Heat one of the boiling tubes for some time. Add equal amount of diluted HCl to both the boiling tubes. 

b. The Essential material/Materials Required Mg Ribbon, Cone HCl, dil HCl

Write up  

Take Magnesium Ribbons of equal mass in two test tubes. Add dil HCl to one test tube and dilute HCl to the other in equal volumes.

c. Energy as well as the speed of molecules increases when reactants are heated. That is as temperature increases the number of molecules with three hold energy increases. As a result, the number of effective collisions increases and these rate of reaction also increases.
