Question 3 - Order of Reaction Flashcards
1
Q
What is meant by a first order reaction?
A
Rate is proportional to the partial pressure or concentration of the reactant.
Rate = k dA/dt
2
Q
If the reaction is elementary what might lead is to believe it is first order?
A
Stochiometric coefficient (big number) is 1.
3
Q
How do you calculate the rate constant and half life from the graph of partial pressure against time?
A
k = -gradient
half life, seconds = ln2/k
