rates of reaction - mean rate of reaction Flashcards
1
Q
what does the slope of a line on a graph show us?
A
rate of reaction
2
Q
steeper line =
A
faster rate of reaction
3
Q
steep line at start of graph =
A
a lot of product is made in short time due to having a large number of reactant molecules present so lots reacting / forming new product
4
Q
less steep line =
A
reaction slowing down due to a lot of the reactant molecules already reacted and turned to product so fewer reactant molecules available
5
Q
end slope of line =
A
zero. it is flat. reaction stopped, all reactant molecules have reacted
6
Q
what is gas measured in?
A
cm cubed
7
Q
what is solid measured in?
A
grams
8
Q
mean rate of reaction equation?
A
quantity of product formed / time
