← ScienceWhich outcome increases when platinum's surface area increases?
A)Catalytic reaction turnover rate✓
B)Activation energy barrier height
C)Product equilibrium constant value
D)Molecular diffusion boundary thickness
💡 Explanation
Increasing platinum surface area raises the reaction rate because it increases the number of active sites accessible for reactant adsorption via heterogeneous catalysis. Therefore, the turnover rate increases, rather than the equilibrium constant shifting or barrier heights changing under the same conditions.
