Question

Standard formation reaction of liquid chloroform.

A) CH3Cl(l) → CH4(g) + Cl2(g)
B) C2H5OH(l) + O2(g) → CO2(g) + H2O(g)
C) 2H2(g) + O2(g) → 2H2O(g)
D) NH3(g) → N2(g) + 3H2(g)

Answer 1

None of the provided reactions A) through D) represents the standard formation reaction for liquid chloroform. The formation reaction would involve elements in their standard states combining to form CHCl3(l).

Step-by-step explanation:

When considering standard formation reactions for various compounds, we are looking for a simple reaction that forms one mole of a compound from its elements in their standard states. For chloroform (CHCl3), a proper formation reaction would involve the combination of carbon, hydrogen, and chlorine in their standard states: graphite (solid carbon), H2 (gaseous hydrogen), and Cl2 (gaseous chlorine). None of the reactions A) through D) represent the standard formation reaction for liquid chloroform. The correct standard formation reaction for liquid chloroform would involve combining carbon, hydrogen, and chlorine to directly form CHCl3(l).
