Answer
This option indicates that only the variable X is influenced by the catalyst. However, in many chemical reactions, a catalyst typically impacts multiple reactants or products, not just one.
Step 2
A catalyst appropriate for this reaction will affect the value of Y only.

Answer
This statement suggests that only Y is affected, which underestimates the role of a catalyst. Catalysts generally do not selectively impact a single component.
Step 3
A catalyst appropriate for this reaction will affect the value of X and Z only.

Answer
This option implies that both X and Z are influenced by the catalyst. It is plausible for a catalyst to affect these two variables, but we need to consider if Y is also affected.
Step 4
A catalyst appropriate for this reaction will affect the value of X, Y and Z.

Answer
This is the most accurate response. A catalyst typically speeds up the reaction without being consumed, and it can influence all relevant reactants and products. Thus, it is reasonable to conclude that the catalyst will impact X, Y, and Z.
