If 42.4g of Al react with excess O2 and 67.3g of Al2O3 are produced, what was the percent yield of Al2O3? The Balanced Equation is 4 Al + 3 O2 --> 2 Al2O3

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?

0.042
