11hint; after infinite time all the reactant will be converted into product
In a reaction NH4NO2 → N2(g) + 2H2O (l) the volume of N2 after 20 mins and after a long time is 40ml and 70ml respectively ...the value of rate const is:
a)(1/20)ln(7/4) /min
b)(2.303/1200)log(7/3) /sec
c)(1/20)log(7/3) /min
d)(2.303/20)log(11/7) /min

101this means tht in infinte time the reaction will be complete soo.. we can say NH4NO2 volume of 70 ml
after 20 mins N2 formed is 40 ml ..thus NH4NO2 remaining is 70-40=30ml.
now frst order reaction
ln(AOA) =kt
k=2.303 log(7030) 120
n u get the ans :)
