The first-order reaction, 2 N2O(g) → 2 N2(g) + O2(g), has a rate constant equal to 0.76 s-1 at 1000 K. How long will it take for the concentration of N2O to decrease to 6.0% of its initial concentration? 3.7 s 13 s 0.27 s 17 s

t=3.7 sec this much time it will take

Explanation:

first order: the reaction in which rate depends only on one ractanta and depend linearly.

As given the question that reaction is first order so we will use first order kinetic equation.

Assume that initial concentration is a

then the final concentration is 0.06a

after calculation

t=3.7 sec

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.
