PLEASE HELP Part D
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.

it is the most commonly accepted one

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
