In Contact Process arsenic impurities act as poison for:
Correct answer: B. V2O5
- A. Fe(OH)3
- B. V2O5
- C. Fe2O3
- D. H2S2O7
Explanation
Arsenic impurities can act as poison for catalytic activity. (Fact) In the contact process, the catalyst used is vanadium pentoxide, V2O5, therefore, it will be poisoned by arsenic impurities and decrease the efficiency of the process. Therefore, option B is the correct answer.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
