Use the information to calculate deltaGrxn at 298 K. 3H2(g) +N2(g) 2NH3(g) deltaHrxn = -92.38 deltaSrxn =-198.2 J/K deltaGrxn = ___kJ

deltaGrxn at 298 K. 3H2(g) +N2(g) 2NH3(g) deltaHrxn = -92.38 del

Explanation:

-198.2 J/K deltaGrxn = ___kJ

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
