Words and meanings to learn
observable change
evidence that a reaction has occurred, such as gas production, colour change or temperature change
rate of reaction
how fast a chemical reaction occurs
gradient
the steepness of the tangent line, calculated as change in y ÷ change in x
mean rate
the average speed of a reaction over a set period, calculated using total change ÷ time
tangent
a straight line that touches a curve at a single point, used to find the rate at a specific time
