Lechateliers principle and hydrogen bonding

Question

Assignment:

Question 1. Utilizing Le chatelier's principle, indicate the shift (if any) that would occur to
C₂H₆+heat =C₂H₄+H₂ (explain your reasons)
a) if C₂H₆ is removed from the system
b) if the volume of the container is increased
c) if the temperature is raised

Question 2. Consider the following system at equilibrium N₂+ 3H₂=2NH₃+ 92.5kJ complete the table that follows, indicate changes in moles by entering I,D,N or in the table. (I=increase , D=decrease N=no change?=insufficient information to determine) change of stress direction of reaction change in number of moles imposed on the system at equilibrium left or right to reestablish equilibrium N2 H2 NH3

a) add NH3
b) increase volume of reaction vessel
c) add catalyst
d) add both H2 and NH3

Question 3. In which of the following substances would you expect to find hydrogen bonding? Explain your reason.
a) C2H6
b) NH3
c) H2O
d) HI
e) C2H5OH
for each of the compounds that forms hydrogen bonds draw a diagram of the two molecules using a dotted line to indicate where the hydrogen bonding will occur.
