Give at least two results of too little air being in a running engine.

The answer is:

Due to little oxygen, the fuel does not burn completely and therefore only a small proportion of power of the fuel is harnessed to turn the pistons. This can even cause the engine to stall. Due to incomplete combustion, because there is more fuel than oxygen in each combustion cycle, the exhaust will be darker due to unburned carbon.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?
