Worked Solution & Example Answer:Which statement about the behaviour of a catalyst in this reaction is correct? A - VCE - SSCE Chemistry - Question 16 - 2006 - Paper 1
Step 1
B. It increases the activation energy of the forward reaction only.
Answer
A catalyst functions by providing an alternative reaction pathway with a lower activation energy for both the forward and reverse reactions. Therefore, the correct statement about the behavior of a catalyst is:
Answer: C. It decreases the activation energies of both the forward and back reactions.
A catalyst will not increase the activation energy, as this contradicts its role in facilitating reactions.
