Pcl5 => pcl3+cl2
the no of moles of cl2 produced will be if one mole of pcl5 is heated 250c in vessel having a capacity of 10dm^3. at 250°c kc= 0.041

0.47 moles

Explanation:

Initial moles of   = 1 mole

Volume of container =

Initial concentration of  

The given balanced equilibrium reaction is,

Initial conc.         0.1 M             0    0

At eqm. conc.    (0.1-x) M   (x) M   (x) M

The expression for equilibrium constant for this reaction will be,

Solving for x:

Thus concentration of produced is 0.047 M

where,

n= moles of solute  

= volume of solution in L

Thus moles of produced is 0.47.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
