For the reaction N2O5(g)→2NO2(g)  +  12O2(g),{N_2}{O_5}(g) \to 2N{O_2}(g)\; + \;\frac{1}{2}{O_2}(g), the rate of disappearance of N2O5{N_2}{O_5} is 6.25×10−3  mol  L−1  s−1.6.25 \times {10^{ - 3}}\;\mathrm{mol}\;{\mathrm{L}^{ - 1}}\;{\mathrm{s}^{ - 1}}. The rate of formation of NO2N{O_2} and O2{O_2} will be respectively.
View answer and explanation
Correct option: B
1.25×10−2  mol  L−1  s−1  and  3.125×10−3  mol  L−1  s−11.25 \times {10^{ - 2}}\;\mathrm{mol}\;{\mathrm{L}^{ - 1}}\;{\mathrm{s}^{ - 1}}\;and\;3.125 \times {10^{ - 3}}\;\mathrm{mol}\;{\mathrm{L}^{ - 1}}\;{\mathrm{s}^{ - 1}}
Option B (1.25×10−2  mol  L−1  s−1  and  3.125×10−3  mol  L−1  s−11.25 \times {10^{ - 2}}\;\mathrm{mol}\;{\mathrm{L}^{ - 1}}\;{\mathrm{s}^{ - 1}}\;and\;3.125 \times {10^{ - 3}}\;\mathrm{mol}\;{\mathrm{L}^{ - 1}}\;{\mathrm{s}^{ - 1}}) is correct because it correctly calculates the rates of formation of NO2NO_2 and O2O_2 based on the stoichiometry of the reaction.
