Consider the reaction 2 no2(g) + f2(g) => 2 no2f(g) rate = -δ[f2]/δtwhat is another form of the rate of the reaction?

Explanation:

The rate of a chemical reaction can be measured as how many of moles of a substrate are consumed of moles of products are produced. So it can be expressed as the change in molar concentration of reactant or product over time.

In that sense, we must take in account the stoichiometric coefficients of the reaction. For example, each time a reaction takes place, two molecules of react with one molecule of to produce two molecules of .

Also, we use the "-" sign for consumption and leave positive sign for production of a substance.

So, as the question states, one for of expressing the reaction rate is , in other words as the consumption of over time.

But it is also possible to express the reaction rate in terms of the other components.

We can say that , with negative sign for consumption and the (1/2) to normalize the rate. Note that as the stoichiometric coefficient it's two, the rate of consumption will be twice the reaction rate.

With similar reasoning, we can express the rate of the reaction based on the production of , as .

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

we need the questions , i may then you.
