QUESTION 40 Recall that for a reaction A + B C + D the actual AG is related to the standard AGO by the equation: AG = AGO + RTIN([CIJDIAJ[B]). Assuming that AG" = 0, how will the actual AG compare to the standard AGO if the ratio of products to reactants is 10:1? O AG will be negative, so the forward reaction will be favored. O AG will be equal to AG", so the reaction is at equilibrium. O AG will be positive, so the reverse reaction will be favored. O Cannot tell from the information given.
Consider the quilibrium reaction between X and Y, as shown below: X=Y AG The reaction is started with 10 mmol of X; no Y is initially present. After 48 hours, analysis reveals the presence of 10 mmol of X and 0 mmol of Y. Which is the most likely explanation? = −1 - 45 kJ mol X and Y have reached equilibrium concentrations. An enzyme has shifted the equilibrium toward X. Formation of Y is kinetically slow; equilibrium has not been reached by 48 hours. Formation of Y is thermodynamically unfavorable. Two of the above explanations are reasonable.
