Qno.1
When temperature is lowered reaction is happening slowly because
1. Decrease in temperature will lower the average kinetic energy of molecules
Hence energy is lowered.
2. Decrease in temperature reduces the diffusion of molecules. So all molecules would be close. With number of molecules more, energy would be less thus making the reaction slower.
Qno2
How catalyst increases rate of reaction?
i. A catalyst lowers the activation energy and as a result rate of reaction is faster.
ii. Catalysts cause reactant particles to contact each other...
