Answer: The value of the equilibrium constant Kc for this reaction is 3.72
Explanation:
Equilibrium concentration of
= 
Equilibrium concentration of
= 
Equilibrium concentration of
= 
Equilibrium concentration of
= 
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For the given chemical reaction:
The expression for
is written as:
Thus the value of the equilibrium constant Kc for this reaction is 3.72
Answer:
The athlete should consume about 476 g of carbohydrates per day to maintain a good storage of glycogen in his body
Explanation:
For an athlete who trains daily, 5 to 7 g of carbohydrates per Kg of body weight per day is recommended;
∴ m athlete = (175 Lb)×(0.453592 Kg/Lb) = 79.3787 Kg
⇒ m carbohydrate = (79.3787 Kg)×( 6 g carbohydrate/ Kg.day) = 476.27 g carbohydrate/day
