Which situation best describes a successful collision (one that leads to a chemical reaction)?
Collision theory predicts which of the following?
Which of the following is a bimolecular reaction?
The rate of a chemical reaction will increase with
Reaction rate decreases if the frequency of collisions
Why is the reaction below, unlikely to take place in a single, elementary step?
A + 2B + C → Products
Consider the reaction shown below that takes place in two, elementary steps that make up a more complex, overal reaction.
Step 1: O
3(g) + HO (g) → HO 2(g) + O 2(g)
Step 2: HO 2(g) + O (g) → HO (g) + O 2(g)
What is the molecurality of the second step?
In a reaction where a very large proportion of the molecules involved have energies that are equal to or greater than the activation energy, it is observed that the reaction is still relatively slow. What is the most reasonable explanation for this?
What is the molecularity of the elementary reaction shown below?
2HI → H
2 + I 2
Which of the following will be found at the highest energy on a reaction enthalpy profile?
