Question
G"' for the reaction ADP + Pi ? ATP is +30.5 kJ/mol. If all of the products and reactants are initially present at 1M, what can you say about the relative concentrations of ADP, Pi, and ATP at equilibrium (assume standard conditions of pH and temperature)? O AThe concentration of ADP, Pi, and ATP will all equal 1 M. ADP and Pi will have concentrations less than 1M, and ATP will have a concentration greater than 1 M. ADP and Pi will have concentrations greater than 1 M, and ATP will have a concentration less than 1M. ADP and Pi will have concentrations greater than 1 M, and ATP will have a concentration of 1M. O E ATP will have a concentration greater than 1 M, and ADP and Pi will have concentrations less than 1 M. ATP will have a concentration greater than 1 M, and ADP and Pi will both have concentrations of 1 M.Explanation / Answer
ADP+Pi--->ATP
G=+35units
Since del G is positive, reaction will not take place and concentration of reactants and products will remain same, i.e. 1M.
Thus, correct choice should be A.
