Rate of Reaction Flashcards
1
Q
what are the two ways we can calculate rate of reaction
A
use mass of reactants consumed
OR
use mass of products made
2
Q
what is the rate of reaction equation (2)
A
rate = mass of reactants consumed(g)/ time (seconds)
rate = mass of products gained(g)/ time(seconds)
3
Q
what is rate measured in
A
grams per second g s^-1
4
Q
how do we calculate rate at specific points on graphs
A
draw a tangent to point and work out gradient
5
Q
what usually happens in reactions (graph)
A
chemicals run out so reaction rate slows down and gradient less steep
