What are rate graphs?
What are rate graphs?
Visual tools showing reactant/product changes over time
Why do rate graphs show curves?
Why do rate graphs show curves?
Rate of reaction changes as reaction progresses
Direction of reactant curve
Direction of reactant curve
Slopes downwards (reactants used up)
Direction of product curve
Direction of product curve
Slopes upwards (more product made)
Where is curve steepest on rate graph?
Where is curve steepest on rate graph?
At beginning (reaction fastest here)
Why is reaction fastest at beginning?
Why is reaction fastest at beginning?
Plenty of reactant particles available to collide
Curve steepness as reaction continues
Curve steepness as reaction continues
Becomes less steep (fewer particles to collide)
What does plateau on rate graph mean?
What does plateau on rate graph mean?
Reaction stopped (no reactants left or equilibrium)
How to find rate from graph
How to find rate from graph
Calculate gradient (slope) of curve
What is a tangent on rate graph?
What is a tangent on rate graph?
Straight line touching curve at point without crossing
