In the first 11.0 s s of the reaction, 1.6×10−2 mol mol of O2O2 is produced in a reaction vessel with a volume of 0.500 L L . What is the average rate of the reaction over this time interval?

The answer to the question is;

The average rate of the reaction over the 11 seconds time interval is

1.455×10⁻³ mol/s.

Explanation:

To solve the question, we note that

Quantity of O₂ produced = 1.6×10⁻² mol

Reaction time = 11 seconds

Volume of reaction = 0.5 L

The rate of a chemical reaction is given by

Average rate of reaction =

Average rate of production of O₂ k = = 1.455×10⁻³ mol/second.

your parents i think this could be it

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.
