How do catalysts at a solid surface affect reactant molecules?
Options
- AThey increase the temperature of the reactants
- BThey decrease the concentration of reactants
- CThey form bonds with reactant molecules
- DThey increase the pressure of the reactants
Correct answer
C. They form bonds with reactant molecules
Step-by-step solution
Catalysts at a solid surface involve the formation of bonds between reactant molecules and atoms of the surface of the catalyst (first row transition metals utilise 3d and 4s electrons for bonding).
