Why is the answer positive?Homework Answers
T = 298 K
use:
ΔGo = -R*T*ln Kc
= - 8.314*298* ln(8.9*10^-2)
= 5993 J/mol
= 5.993 KJ/mol
After rounding it becomes 6.0 KJ/mol
Answer: B
Answer will be positive beacase Keq < 1 which means reaction is non sponatneous
Add Answer to:
Why is the answer positive?
