What else can I help you with?
What is the entropy change for the third reaction below N2(g) plus O2(g) 2NO(g) and 8710H 180 kJ 2NO2(g) 2NO(g) plus O2(g) and 8710H 112 kJ N2(g) plus 2O2(g) 2NO2(g)?
The equation is: N2(g) + 2O2(g) -> 2NO2(g) Given enthalpy changes: 2NO(g) + O2(g) + 112 kJ -> 2NO2(g) N2(g) + O2(g) -> 2NO(g) + 180 kJ Using Hess's Law, we subtract the second equation from the sum of the first and third equations: 2NO2(g) - (2NO(g) + O2(g)) = 2NO2(g) - 2NO(g) - O2(g), resulting in the entropy change for the third reaction.
Is the equation 2NO O2 - NO2 balanced why or why not?
2NO + O2 --> NO2 is not balanced. There are two nitrogen atoms on the left and only one on the right. There are four oxygen atoms on the left and only one on the right. The correct balanced equation is 2NO + O2 --> 2NO2.
Which of the following is a statement of Hess's law?
All the reactions in a path are added together.
What is the equilibrium constant for the reaction N2(g) O2(g) 2NO(g)?
More NO would form
Why does oxygen increase 2NO plus O2--2NO2 when you add heat?
When heat is applied to the reaction 2NO + O2 → 2NO2, the activation energy required for the reaction to take place is provided. This allows the molecules to overcome the energy barrier and react at a faster rate, leading to the formation of nitrogen dioxide (NO2) from nitrogen oxide (NO) and oxygen (O2).

N2 plus o2 plus HEAT equals 2NO?
Endothermic

What is the equilibrium constant for the reaction N2(g) O2(g) 2NO(g)?
More NO would form
What kind of reaction is N2 plus O2 plus Heat 2NO?
endothermic
How do you balance NO O2 yields NO2?
First, capitalization matters in chemistry. The proper formula for nitrogen monoxide (nitric oxide) is NO. No is the symbol for the element nobelium. The balanced equation is 2NO + O2 --> 2NO2
2NO g plus O2 g yields 2NO2 g?
-144.14 KJ
Which of the following reactions shows that the formation of NO2 requires 33.1 kJ mol?
1/2 N2(g) + O2(g) + 33.1 kJ NO2(g)
What would happen if NO were added to N2(g) plus O2(g) 2NO(g) at equilibruim?
more N2 and O2 would form
What would happen if NO were added to N2(g) O2(g) 2NO(g) at equilibrium?
More N2 and O2 would form
