#C6.2.1
describe the effect on rate of reaction of changes in temperature, concentration, pressure, and surface area
#C6.2.2
explain the effects on rates of reaction of changes in temperature, concentration and pressure in terms of frequency and energy of collision between particles
#C6.2.3
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
#C6.2.4
describe the characteristics of catalysts and their effect on rates of reaction
#C6.2.5
identify catalysts in reactions
#C6.2.6
explain catalytic action in terms of activation energy
#C6.2.7
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
#C6.2.8
interpret rate of reaction graphs
#C6.2.9
interpret graphs of reaction conditions versus rate
an understanding of orders of reaction is not required
#C6.2.10
use arithmetic computation and ratios when measuring rates of reaction
#C6.2.11
draw and interpret appropriate graphs from data to determine rate of reaction
#C6.2.12
determine gradients of graphs as a measure of rate of change to determine rate
#C6.2.13
use proportionality when comparing factors affecting rate of reaction
#C6.2.14
describe the use of enzymes as catalysts in biological systems and some industrial processes
