Humans are heterotrophs that consume food for energy. These foods comprise of sugars that are broken down by enzymic activity within the body for producing energy. This process, called cellular respiration, occurs according to the chemical equation:  C6H12O6(aq) + 6O2(g) 6CO2(g) + 6H2O(i) At equilibrium, the concentration of the reactants and products are determined as [CO2] = 0.30 M, [O2] = 0.040 M and [C6H12O6] = 0.065 M. Determine the value of the equilibrium constant (Kc) and predict whether the products or reactants will be favoured at equilibrium. Given that the concentrations of the reactants and products at a particular time are [co2] =0.65M, [O2] =0.020M and [C6H12O6] = 0.55M, determine the reaction quotient (Qc). Compare the Kc and Qc values and predict the favoured direction of the reaction.

Humans are heterotrophs that consume food for energy. These foods comprise of sugars that are broken down by enzymic activity within the body for producing energy. This process, called cellular respiration, occurs according to the chemical equation: 

C6H12O6(aq) + 6O2(g) 6CO2(g) + 6H2O(i)

At equilibrium, the concentration of the reactants and products are determined as [CO2] = 0.30 M, [O2] = 0.040 M and [C6H12O6] = 0.065 M. Determine the value of the equilibrium constant (Kc) and predict whether the products or reactants will be favoured at equilibrium.

Given that the concentrations of the reactants and products at a particular time are [co2] =0.65M, [O2] =0.020M and [C6H12O6] = 0.55M, determine the reaction quotient (Qc). Compare the Kc and Qc values and predict the favoured direction of the reaction.
