Question

Which of the following factors will be favourbale for higher yields of NO in the reaction given below ?
`N_(2)+O_(2)hArr 2NO(g) (DeltaH=+ve)`
A. Low temperature, high pressure and high conentration of `N_(2) and O_(2)`
B. High temperature, and high concentrations of `N_(2) and O_(2)` . The reaction remains unaffected by pressure.
C. High temperature , law pressure and low concentration, of `N_(2) and O_(2)`
D. Law temperature, low pressure and high concentraion of `N_(2) and O_(2)`

Answer 1

Correct Answer - B
`N_(2)O_(r)hArr2NO(g)(DeltaH=+ve)`
`Deltan=(+ve)` Endothermic Reaction
`Deltan=P_("mole") -R_("mole")`
=2-2=zero
So, reaction remain unaffected pressure Endothermic `Tuarr` high concentration.
