Chemical Thermodynamics Quiz

sc19.7 Free Energy and the equilibrium constant

All processes occur under standard conditions at 298 K unless stated otherwise.
Please round your answers to the hundredths place (e.g. 1.01 g) and try to get within 2% of the correct answer.
You can enter your answers in decimal notation, or you can enter them in scientific notation using 'E' or 'x 10^' for the power of 10 (e.g., enter 6.02 x 10²³ as 6.02E23 or 6.02x10^23).
