Answer:
0.1739
Explanation:
0.800 mol of N2
0.200 mol of H2
0.150 mol of CH4
Total moles of the mixture = 0.8 + 0.2 + 0.150 = 1.150 mol
Mole fraction of H2 = Number of moles of H2 / Total moles
Mole Fraction = 0.2 / 1.150 = 0.1739
That is the definition of pressure. The amount of force exerted over a certain area: N/m^2 (Newtons per square metre).
Heating up a reaction does increase the number of collision only.
Hence, Option C is correct answer.
<h3>What is Collision Theory ? </h3>
According to the collision theory, the reaction take place when the collision occur and molecules having sufficient energy or threshold energy for collision.
The collision of molecules depend on the kinetic energy of molecules. Greater the kinetic energy greater the number of molecules collide. Lesser the kinetic energy lesser will be collision.
<h3>How temperature affect the collision theory ?</h3>
With an increase in temperature, there is an increase in energy that can be converted into activation energy in a collision, and that will increase the reaction rate. A decrease in temperature would have the opposite effect. With an increase in temperature, there is an increase in the number of collision.
Thus from the above conclusion we can say that Heating up a reaction does increase the number of collision only.
Hence, Option C is correct answer.
