In air at 25 °C and 1.00 atm, the N₂ concentration is 0.01 M and the O₂ concentration is 0.033 M. The reaction N₂(g) + O₂(g) → 2NO(g) has Kc = 4.8 x 10-³1 at 25 °C. Taking the N₂ and O₂ concentrations given above as initial values, calculate the equilibrium NO concentration that should exist in our atmosphere from this reaction at 38 °C, Kc = 1.0E-29. Make simplifying assumptions in your calculations. (Express your answer in scientific notation.) [NO] = i M

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.
