4g each of aluminium foil and aluminium powder were introduced respectively into flasks P and Q. Flask P was treated with warm bench sodium hydroxide and all the aluminium dissolved in one hour. Flask Q was treated with cold sodium hydroxide and all the aluminium dissolved in 10 minutes. What was responsible for Q reacting faster than P?
A. There were more aluminium atoms in Q than P B. The heat given off in retarded the reaction C. Q generated more pressure than P during the reaction D. P generated more pressure than Q E. Q has a greater surface area for the reaction than P
