In an analysis of the following reaction at a certain temperature, Br2(g) + Cl2(g) ⇌ 2BrCl(g)the equilibrium concentrations were found to be [Br2] = 4.5 ×10−3 M, [Cl2] = 2.6 ×10−2 M, and [BrCl] = 1.6 ×10−2 M. Write the equilibrium expression, and calculate the equilibrium constant for this reaction at this temperature.

The equilibrium expression is Equilibrium constant =  

Kc or equilibrium constant for this reaction is 0. 55 x

Explanation:

Br2(g) + Cl2(g) ⇌ 2BrCl(g)

Equilibrium constant =  

Kc =   equation 1

      the concentration of diatoms will be divided by 2

1.3 x 10^-2 is concentration of chlorine

0.45 x 10^-2 is concentration of bromine

1.6 ×10−2 is concentration of BrCl2

Putting the values in equation 1 to calculate equilibrium constant.

Kc=    

Kc =  

Kc= 0.55 x 10^2

equilibrium constant for this reaction is 0.55 x

the molar concentration or partial pressure of the gases is taken to find the equilibrium constant.

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance
