Describe and explain how the rate of this reaction changes when the concentration of sulfuric acid is decreased. All other conditions stay the same.
Describe and explain how the rate of this reaction changes when large pieces of cerium are used instead of cerium powder. All other conditions stay the same.
The reaction of cerium with sulfuric acid is exothermic. Complete the energy profile diagram so it shows the enthalpy change for this reaction.
Calculate the maximum volume of hydrogen, in $\text{dm}^3$, obtained when $12.6\,\text{g}$ of cerium reacts with excess sulfuric acid at room temperature and pressure. [$A_r: \text{Ce},140$]
Cerium carbonate has the formula $\text{Ce}_2(\text{CO}_3)_3$. Calculate the percentage by mass that is due to cerium in cerium carbonate.
