← ScienceWhich reaction rate outcome during ammonia synthesis shifts when iron catalyst surface area increases?
A)Equilibrium shifts towards reactant formation
B)Activation energy significantly reduces
C)Overall reaction order increases sharply
D)Reaction rate increases proportionally✓
💡 Explanation
An increased surface area boosts reactant adsorption via increased active sites, so the reaction rate increases proportionally because increased catalyst means more collisions leading to product formation; therefore rate goes up, rather than equilibrium shifts given constant concentrations..
