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

more info ? ? i don't understand what the question is

explanation:

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
