Answer:
Explanation:
A catalyst is a substance that increases the rate of a chemical reaction without itself getting consumed in the reaction as it helps in decreasing the activation energy. Thus, rate of reaction also increases.
A positive catalyst helps in increasing the rate of a chemical reaction whereas a negative catalyst decreases the rate of a chemical reaction.
Whereas when we increase the temperature then collisions between the particles increases due to increase in kinetic energy. Hence, rate of reaction increases with increase in temperature.
Thus, we can conclude that out of the given options adding a positive catalyst will increase the rate of a chemical reaction.

Answer:
The correct answer is: Prepositional phrases don't include verbs.
Explanation:
Infinitive phrases can function as nouns, adjectives, or adverbs. An infinitive phrase begins with an infinitive (to+ simple form of the verb) and includes objects and modifiers.
For example:
<u>to kill a mockingbird</u>
A prepositional phrase is a group of words that consists of a preposition and a noun or a preposition and a pronoun. A prepositional phrase modifies a verb or a noun and it does not contain either a verb or a subject and it functions as a unified part of speech.
For example:
The shirt <u>with flowers</u> is mine.
The main difference between an infinitive and prepositional phase is the fact that <u>prepositional phrases don’t include verbs</u>. If the phrase follows a verb, then it is an infinitive phrase, as the prepositional phrases do not contain verbs.
Tom and Daisy attend a party at Gatsby's place the next Saturday night. Tom has no desire to attend the party, but his loathing for Gatsby makes him want to keep an eye on Daisy.
