If you selected "Not an order of reaction" in the questions above, give a reason for your choice..
As time increases, concentration cannot progress in a straight line.
As time increases, concentration of reactants cannot increase.
As time increases, concentration of reactants must reach zero.
All graphs above represent an order of reaction.
In a rate equation, what is the value "k"
1/ reaction rate
The rate of reaction
The rate constant
The rate derivative
What is the rate equation of this graph?
Rate = k/[A]²
Rate = k/[A][A]
Rate = k
Rate = k/[A]
What is the rate equation of this graph?
Rate = k/[A]²
Rate = k/[A][A]
Rate = k
Rate = k/[A]
What is the rate equation of this graph?
Rate = k/[A]²
Rate = k/[A][A]
Rate = k
Rate = k/[A]
What is the correct rule for "k" in a reaction?
The greater the value of "k", the faster a reaction will go
The greater the value of "k", the slower a reaction will go.
"k" has no effect on the reaction rate as it is constant.
"k" is variable and therefore has no effect on the reaction rate.
In which order of reaction is the rate not dependant on concentration?
None
Zeroth order
First order
Second order
In a first order reaction, what happens to the half-life (t½) as the reaction progresses?
The half-life doubles.
The half-life halves.
The half-life remains constant.
The half-life is exponential.
