Consider the reaction of A being converted into B at 25°C. If the ΔG° of this reaction is the K_eq is ________ and the % conversion is ________.

We can use the relationship between ΔG° and K to find the equilibrium constant for the reaction:

ΔG° = -RT lnK

Solving for K, we get:

K = e^(-ΔG°/RT)

Plugging in the given values, we get:

K = e^(-11eab5e1_c8c5_8be4_9bae_f59b3a2184ad_TB6199_11/(8.314 J/mol*K * 298 K)) = 2.3

Using the equilibrium constant and the stoichiometry of the reaction, we can find the percentage conversion of A to B:

K = [B]/[A] = (x/[A]0)/(1-x), where x is the fraction of A that has reacted and [A]0 is the initial concentration of A.

Solving for x, we get:

x = K[A]0/(1+K[A]0) = 0.7

Therefore, the % conversion is 70%, which is closest to answer choice D, 2.3; 70%.
