describe the effect on rate of reaction of changes in temperature, concentration, pressure, and surface area
describe the effect on rate of reaction of changes in temperature, concentration, pressure, and surface area
explain the effects on rates of reaction of changes in temperature, concentration and pressure in terms of frequency and energy of collision between particles
explain the effects on rates of reaction of changes in the size of the pieces of a reacting solid in terms of surface area to volume ratio
describe the characteristics of catalysts and their effect on rates of reaction
identify catalysts in reactions
explain catalytic action in terms of activation energy
suggest practical methods for determining the rate of a given reaction including: PAG8
for reactions that produce gases: i. gas syringes or collection over water can be used to measure the volume of gas produced ii. mass change can be followed using a balance
measurement of physical factors: iii. colour change iv. formation of a precipitate
interpret rate of reaction graphs
interpret graphs of reaction conditions versus rate
an understanding of orders of reaction is not required
use arithmetic computation and ratios when measuring rates of reaction
draw and interpret appropriate graphs from data to determine rate of reaction
determine gradients of graphs as a measure of rate of change to determine rate
use proportionality when comparing factors affecting rate of reaction
describe the use of enzymes as catalysts in biological systems and some industrial processes
