Consider the following equation in chemical equilibrium.
c2h4(g) + h2(g) = c2h6(g) + 137 kj
what happens to the amount of ethane (c2h6) when the temperature of the system is increased?
a. the amount of ethane decreases.
b. the amount of ethane increases initially and then decreases.
c. the amount of ethane increases.
d. the amount of ethane decreases initially and then increases.

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
