What is the rate law equation?
Think about what each symbol represents.
If [A] = 2 mol/L, and the order with respect to [A] is 1, what happens to the rate if [A] is doubled?
Consider the definition of first-order reactions.
What does the rate law express?
Focus on the main components of the rate law.
True or False: A first-order reaction's rate is directly proportional to its reactant concentration.
Think about how first-order reactions behave.
A reaction has the following rate law: Rate = k [NO]²[Cl₂]. If the concentration of NO is doubled and Cl₂ remains constant, how will the rate of reaction change?
Calculate the effect by applying the exponent of the concentration change.
Using the Arrhenius equation, if the activation energy of a reaction is lowered by 10 kJ/mol, how will this likely affect the rate of reaction at a given temperature?
Consider how activation energy relates to the energy distribution of molecules.
