For the first order reaction
2N2O5(g) → 4NO2(g) + O2(g)           [JEE 2011]
  • a)
    The concentration of the reactant decreases exponentially with time.
  • b)
    The half-life of the reaction decreases with increasing temperature.
  • c)
    The half-life of the reaction depends on the initial concentration of the reactant.
  • d)
    the reaction proceeds to 99.6% completion in eight half-life duration.
Correct answer is option 'A,B,D'. Can you explain this answer?

It varies exponentially with the concentration.....see theory.And b option is also correct,because half life varies in inverse proportion to the Temperature and is independent of the concentration d option can also be proved with the half life formula for 1 order reaction.

For the first order reaction2N2O5(g) → 4NO2(g) + O2(g) [JEE 2011]...
C is incorrect because according to equation t(half life)= 1/(concentration)^(n-1) where n is the order of the reaction
