1
Q
What is the rate of chemical reaction defined as?
A
the change in concentration of reactant or product per unit time
2
Q
What does changing the concentration of substances taking part in a reaction do?
A
usually (but not always) change the rate of reaction (rate equation shows this mathematically)
3
Q
What is the general rate equation?
A
Rate = k[A]m [B]n
k= rate constant
A] = concentration of reactant A (moldm-3)
[B] = concentration of reactant B (moldm-3)
m = order of reaction with respect to A
n = order of reaction with respect to B
4
Q
What is the order of reaction?
A
a measure of how a reactant affects the rate of reaction
5
Q
what can the orders only be?
A
zero[A]0, first[A]1 or second[A]2
6
Q
what are rate constants dependent on?
A
temp
