- Rate and Extent of Chemical Change
- Rate of Reaction
- The rate of chemical reaction is how fast the reactants are changed into products.
- Slow reactions include the rusting of iron and chemical weathering.
- Burning is a fast reaction but explosions are even faster and release a lot of gas.
- Reactions with a moderate speed include magnesium fizzing in acid.
- Particles must collide with enough energy in order to react
- The more often particles collide, the faster the reaction.
- Heat energy is produced when particles collide more frequently.
- Rate of Reaction depends on five factors:
- Concentration of a solution
- The higher the concentration of the solution, the faster the rate of reaction.
- The presence of a catalyst
- The catalyst speeds up the rate of reaction without being used up.
- Surface Area
- Increasing the surface area increases the rate of reaction.
- Temperature
- Increasing the temperature increases the rate of reaction
- Pressure of a gas
- The higher the pressure, the faster the rate of reaction.
- Concentration of a solution
- The rate of chemical reaction is how fast the reactants are changed into products.
- Reversible Reactions
- Reversible reactions will reach equilibrium.
- Reversible reactions can be exothermic or endothermic.
- One example of a reversible reaction is anhydrous copper sulfate and hydrous copper sulfate.
- Le Chatelier's Principle
- Le Chatelier's Principle is the idea that if you change the conditions of a reversible reaction at equilibrium, the system will try to counteract that change.
