In part D of task 1, you identified at least two ways in which the reaction of nitrogen and hydrogen could be changed to alter the equilibrium. Use the simulation to test those changes. Describe how you used the simulation to model the changes and the results they produced. Use these methods if you find them helpful: Look at the pie graph to see how the system changes.
Use the Temperature slider at the bottom to cool or heat the mixture.
Click the pause button on the simulation to observe the number of particles at any point of time.

tracks, burrows, eggshells, nests, tooth marks, or gastroliths

elements make up everything, and they combine to make compounds.

the answer is c

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
