Question

The decomposition of nh3 on platinum surface is zero order reaction. If rate constant is 4*10^-3 how long will it take to reduce the initial concentration

Answer 1

Missing point in question :-

how long will it take to reduce the initial concentration of NH3 from 0.1 to 0.064 M

Answer :- The rate is reaction is constant

∴ d [NH3] / dt = k

∴ d [NH3] / dt = 4 x 10⁻³

t = 4 x 10⁻³/ (0.1 - 0.064)

∴ t = 1/9 sec

Answer 2

Answer:9
