Chap 7 Igcse Chemistry Notes Pdf Reaction Rate Catalysis

Chap 7 Igcse Chemistry Notes Pdf Reaction Rate Catalysis Use equations below to find the rate of reaction to compare the effect of changes in surface area particle size, concentration, temperature, use of a catalyst etc. Rates of reaction rate is a measure of how fast a reaction goes, its speed. the rate of a chemical reaction is the speed at which the reactants are used up or the speed at which new products are formed. in order to measure the rate of a reaction you need to measure a change (for example in mass, or volume or colour) over a period of time.

Igcse Chemistry Rates And Equilibrium Pdf Catalysis Reaction Rate You should be able to recall how changing the concentration, pressure, temperature, and surface area afect the rate of a reaction. increasing the number of successful collisions means that a greater proportion of reactant particles collide to form product molecules. Uses of transition metals the hard strong transition metals are used in structure such as bridges, buildings, cars etc. many transition metals are used in making alloys. transition metals are used as conductors of heat and electricity. many transition metals and their compounds act as catalysts. A catalyst speeds up the rate of reaction. this is because the catalyst provides an alternate reaction pathway with a lower activation energy so less energy is required for a successful collision. A catalyst increases the rate of a reaction by providing an alternative reaction pathway with lower activation energy. catalysts are not consumed in the reaction and can be reused.

A catalyst increases the rate of a reaction by providing an alternative reaction pathway with lower activation energy. catalysts are not consumed in the reaction and can be reused. When answering questions on the effect of concentration on the rate of reaction, you should mention that there are more particles per unit volume (usually cm3) and this causes an increase in the rate of collisions.
