- Rates of Reaction and Equilibrium
- you can measure rate of chemical reaction by monitoring the amount of reactants used up over time.
- Alternatively you can measure the rate of reaction by measuring the amount of products made over time.
- Collision Theory and surface area
- Particles must collide, with a certain minimum amount of energy this is called activation energy of reaction.
- The rate of chemical reaction increases if the surface area to volume ratio of any solid reactants increases.
- The effects of temperature
- Reaction happen more quickly as the temperature increases.
- increases temperature also increases the rate of reaction because particles collide more frequently and energetically
- Reaction happen more quickly as the temperature increases.
- The effect of concentration and pressure
- increasing the concentration of reactants in solutions increases the frequency of collisions between particles and so increases rate of reaction
- The effect of catalyst
- A catalyst speeds up the rate of reaction, but is not used up itself n the reaction.It remains chemically unchanged.
- they're used whenever possible in industry to increase rates or reaction and too reduce energy costs.
- A catalyst speeds up the rate of reaction, but is not used up itself n the reaction.It remains chemically unchanged.
