Concentration-Time Graphs (AQA A-Level Chemistry): Flashcards

Straight line with negative gradient

Curve sloping down, steep then flattening

Steeper initially, flattens more than first-order

Calculate gradient (slope) at that point

Tangent to curve at $t = 0$

Draw tangent at point, calculate gradient

Constant half-life

$k = -\text{slope}$ of conc-time graph

$\text{mol dm}^{-3} \text{ s}^{-1}$
