Consider the combustion of ethylene: c2h4(g)+3o2(g)→2co2(g)+2h2o(g) if the concentration of c2h4 is decreasing at the rate of 3.6×10−2 m/s , what is the rate of change in the concentration of co2? express the rate in molarity per second to two significant digits.

- Rate in change of carbon dioxide is \frac{7.2*10^-^2m}{s}[/tex] .

Solution:- For the given reaction the rate could be written as:

rate =

Here the negative sign indicates a decrease in concentration of the reactants and the coefficients are inverted. For example the coefficient of is 2, so it is written as .

From above expression,

Let's plug in the value for the rate of decrease in concentration of ethylene.

So, the rate in change(increase) of carbon dioxide is .

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
