Challenge Problems
Push your limits with challenges.
Question 1
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?
💡 Hint: Calculate the effect by applying the exponent of the concentration change.
Question 2
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?
💡 Hint: Consider how activation energy relates to the energy distribution of molecules.
