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 .

0
