- More quick
- More quickly
- As quickly more
- None of these
The correct answer is “more quickly” because it is the correct comparative form of the adverb “quickly.” When comparing the rate of a reaction (how quickly it occurs), we use the comparative form. Since “quickly” is an adverb with more than one syllable, its comparative is formed with “more” rather than the suffix “-er.” The phrase “more quick” is grammatically incorrect because “quick” is the adjective form; the adverbial form must be used to modify the verb “react.” “As quickly more” is syntactically flawed and not a standard comparative structure. Therefore, “more quickly” is the only grammatically correct option to describe the comparative speed of the chemical reaction.
