In this reaction, a gaseous system with a volume of 3.00 L has a rate of formation of NOCl of 0.0120 M s-1 . The volume of the system is decreased to 1.00 L with no change of temperature. What is the new rate of formation of NOCl?

x = 0.324 M s⁻¹

Explanation:

Equation for the reaction can be represented as:

 2 NO(g)   + Cl₂ (g)      ⇄     2NOCl (g)

Rate = K [NO]² [Cl₂]

Concentration =

from the question; their number of moles are constant since the species are quite alike.

As such; if Concentration varies inversely proportional to the volume;

we have: Concentration ∝

Concentration =

Similarly; the Rate can now be expressed as:

Rate = K [NO]² [Cl₂]

Rate =

Rate =

We were also told that the in the reaction, the gaseous system has an initial volume of 3.00 L and rate of formation of 0.0120 Ms⁻¹

So we can have:

0.0120 =

0.0120 =   -----Equation (1)

Now; the new rate of formation when the  volume of the system decreased to 1.00 L can now be calculated as:

x =

x = 1             ------- Equation (2)

Dividing equation (2) with equation (1); we have:

=

=

x = 0.0120 × 27

x = 0.324 M s⁻¹

∴  the new rate of formation of NOCl = 0.324 M s⁻¹

i think a, hope it .

explanation:

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
