23. Of the following reactions, the one affected by the surface area is:
a. 2NH3 (g) <--> N2 (g) + 3H2 (g)
b. NaNO2 (ac) + HCl (ac) -> NaCl (ac) + HNO2 (ac)
C. H2 (g) + CaO (s) -> Ca (s) + H2O (l)
d. all of the above
Homework Answers
When the reactants are solid and liquid or the reactants are solid and gas the reaction occurs at the surface of the solid.HENCE at this point surface area plays a key roll on increasing or decreasing the rate of the reaction.With increase in surface area will increase the rate of reaction. Among the given option only the reaction where hydrogen gas react with solid calcium oxide is an example of solid and gas reactant.
