*CHEMICAL KINETICS Collision theory and rates of reaction *One of the main considerations when examining chemical reaction is whether it will take place fast enough for it to be useful. *In other words‚ there’s no point carrying out a reaction if it takes 150 years to form the product! *Many chemical reactions occur very quickly. *Studying Reaction Rates *Defined as the change in concentration of reactants of products per unit time. *Units: mol dm¯³ s¯¹ *Rate of Reaction * ‚ the

The experiment was conducted at the Human Kinetics Program (HKP) Building in the University of the Philippines – Baguio. The terrain was prepared by distributing an even layer of gravel on the ground‚ and the background was covered by black cloth spanning the length of the terrain. The subject was also dressed in black to match with the background. The boules‚ jack‚ and significant joints and points on the subject’s body were marked with green bands to contrast with the background. A throwing circle

Electron pair geometry: This geometry includes all the electron pairs (bp + lp) around the central atom. Molecular geometry: This includes only placement of atoms (bp) in the molecule. When there is no lone pair in molecules the two geometries are same. PART C VSEPR Theory (Valence Shared Electron Pair Repulsion Theory) Syllabus: Various rules under VSEPR theory to explain molecular geometry (following examples may be taken to explain various rules- BeCl2‚ BF3‚ CH4 ‚ NH4+ ‚ PCl5 ‚ SF6‚
