A mixture of nitrogen and oxygen in a 1:3 ratio has a volume of 4.00 L. What is the volume of the nitrogen trioxide when the nitrogen and oxygen
react according to the equation:
N2 (g) + 3 02 (g) → 2 NO, (g)
while keeping pressure and temperature constant?
lol

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

here are some of the ways in which chemical and nuclear reactions differ.
