For the reaction N2(g) + 3H2(g) == 2NH3(g), what will happen if more nitrogen gas is added?

A. there will be a shift towards the products
B. there will be a shift towards the reactants
C. there will not be a shift in equilibrium
D. the value for Keg will change

Idon't hope someone you

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

For lesson: cameras, plant presses, newspaper, paper towels, clip boards, pencils, calculators, field guides, metric measuring tapes, paper, transect squares, colored pencils, ph meters, light meters, computers, etc.for extension: baggies for soil samples collecting, distilled water, hand shovels, beakers, boiled rice, microscopes, well microscope slides or regular microscope slides with cover slips
