Chapter 6, Problem 38E

a)

Interpretation Introduction

Interpretation: Whether system with PH2O of 1.00 atm , PCl2O of 1.00 atm and PHOCl of 1.00 atm is at equilibrium or not should be determined. Also, shift in system direction if it is not at equilibrium should be determined.

Concept introduction:Chemical equilibrium is taken into consideration if rate of forward and backward reactions become equal. At this stage, reactants and products have constant concentration. Equilibrium constant is denoted by K .

Reaction quotient is determined with help of initial concentrations of reactants and products. It is denoted by Q . If system is not in equilibrium, direction of shift is determined by comparison of Q and K . Below mentioned are three cases to determine shift of reaction direction.

1. If Q and K are equal, equilibrium is attained and no shift in direction is observed.

2. If Q is greater than K , shift in left direction is observed. This results in more consumption of products and formation of reactants.

3. If Q is less than K , shift in right direction is observed. This results in more consumption of reactants and formation of products.

b)

Interpretation Introduction

Interpretation: Whether system with PH2O of 2.00 torr , PCl2O of 49.8 torr and PHOCl of 21.0 torr is at equilibrium or not should be determined. Also, shift in system direction if it is not at equilibrium should be determined.

Can you please explain to me this problem im very confused and lost. Help me step by step and in detail im soo lost.
2) There are many forms of cancer, all of which involve abnormal cell growth. The growth and production of cells, called cell proliferation, is known to involve an enzyme called protein farnesyltransferase (PFTase). It is thought that inhibitors pf PFTase may be useful as anticancer drugs. The following molecule showed moderate activity as a potential PFTase inhibitor. Draw all stereoisomers of this compound. HO OH
Considering rotation around the bond highlighted in red, draw the Newman projection for the most stable and least stable conformations when viewed down the red bond in the direction of the arrow. Part 1 of 2 H₁₂C H H Draw the Newman projection for the most stable conformation. Select a template to begin. Part 2 of 2 Draw the Newman projection for the least stable conformation. G 心
