Incorrect Question 6 of 14 ncorrect Map Sapling Learning Consider a general reaction enzyme Alaa Baa The AG of the reaction is -8.460 kJ mol Calculate the equilibrium constant for the reaction. (Assume a temperature of 25 C.) Number eq 30.4 What is AG at body temperature (37.0° C) if the concentration of A is 1.6 M and the concentration of Bis 0.75 M? Number AG 9.5 k J. mol Incorrect. The relationship between AG and AG is AG AG RT l Alternatively, using the common logarithm gives AG AG '+2.303RT log "O Previous 3 Give Up & View Solution Try Again Next ExtExplanation / Answer
1)
Go = -8.460 KJ/mol = -8460 J/mol
T = 25oC = 298 K
Go= -R*T*ln K'eq
-8460 = -8.314*298*ln K'eq
K'eq= 30.4
Answer: 30.4
2)
T = 37 oC = (37+273) = 310 K
use:
G = Go + R*T*ln Q
G = Go + R*T*ln {[B]/[A]}
= - 8460 + 8.314*310*ln (0.75/1.6)
= -8460 - 1953
= -10413 J/mol
= -10.4 KJ/mol
Answer: -10.4 KJ/mol
