C (g) + E (g) <-- --> 2 W (g) Initially, there are 3.5 moles of W placed in a 2.5 L evacuated container. Equilibrium is allowed to establish and the value of K = 2.34 E-5 for the reaction under current conditions. Determine the concentration of E at equilibrium.

A. [E] = 8.352 E -6
B. [E] = 0.00578
C. [E] = 0.00289
D. cannot solve using 5% approximation rule

Which of the following would be an accurate picture of the earth during the summer time of the northern hemisphere?

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
