Question

reactions w and x are basically the same chemical reaction. one utilizes an enzyme and the other does not. which of the following statements accurately explains the difference between reactions w and x? select the correct answer. reaction w occurs only at room temperature. reaction x takes longer to come to completion. reaction w requires more energy. reaction x does not utilize an enzyme.

Explanation:

Enzymes are biological catalysts that speed up chemical reactions. Without an enzyme (as in reaction X), the reaction generally proceeds more slowly. Option A about room - temperature is not related to the enzyme factor. Option C is wrong as enzymes lower the activation energy, so reaction with enzyme (W) should require less energy. Option D just restates the given fact without explaining the difference in reaction progress. Option B is correct because the non - enzyme reaction (X) will take longer to complete due to the lack of catalytic action.

Answer:

Reaction X takes longer to come to completion.
