H2 (g) + br2 (g) < => 2 hbr (g)

the equilibrium constant is 13485. at equilibrium the h2 concentration is 0.05 m, while the br2 concentration is 0.023 m. calculate the hbr concentration at equilibrium, to 1 decimal. be careful with the units.

[HBr] = 4.7M at equilibrium

Explanation:

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

consider the reaction below.

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

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
