Acatalyst
1. has no effect on the specific rate constant
for the reaction that it catalyzes.
2. changes the value for the heat of reaction.
3. alters the reaction mechanism.
4. is always a solid.
5. increases the reaction rate but does not
alter the activation energy of the reaction.
6. must be continually replenished as it is
used up.
7. must be present for any reaction to proceed.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
