Challenge Problems
Push your limits with advanced challenges
In a reaction where the steric factor is 0.001, calculate the effective collision frequency if the total collision frequency is 10^6 collisions per second.
💡 Hint: Remember the formula for effective collisions involves multiplying total collisions by the steric factor.
Discuss how increasing the concentration of reactants A and B by 50% will affect the rate of a bimolecular reaction A + B -> C if the steric factor is 0.3.
💡 Hint: Consider how the mathematical relationships for concentration and steric factor interact.
