REaction Rates and Equilibrium

key Concepts

• Chemical reactions don't happen at the same rate 
• There are 2 ways to measure the rate of a reaction
• 1. measuring the rate in which it dissappears
• 2. measuring the rate in which a product appears
• An inhibitor slows down or prevents a chemical reaction from occurring 

Untitled Slide

• A catalyst increases the rate of a chemical reaction
• It can also help with geometry but it's NOT consumed by it
• This means: in order for a reaction to occur the molecule must be 
• .... orientated properly 

Untitled Slide

• The collision theory of reactions:
• Molecules must collide in order to react
• In a successful collision existing bonds are broken while...
• ... new bonds are formed and reactants turn into products
• Activated Complex: highest point on a reaction profile(Transition State)

Untitled Slide

• Endothermic Reaction: absorbs heat, recant lower energy than prodcut
• Exothermic Reaction: releases heat, product lower energy that reactant
• A reversible reaction an go 2 ways occurring at the same time
• Collision of the reacting molecule cause chemical reactions in a closed...
• system

Untitled Slide

• Temperature, Concentration, Particle Size, & Inhibitor all affect the..
• the rate of a chemical reaction
• when temp is higher particles hit each other more often & with..
• more energy which will cause them to react faster
• Heat is either the product or reactant
