For the equilibrium pcl5(g) pcl3(g) + cl2(g), kc = 4.0 at 228°c. if pure pcl5 is placed in a 1.00-l container and allowed to come to equilibrium, and the equilibrium concentration of pcl5(g) is 0.26 m, what is the equilibrium concentration of pcl3?

Answer : The equilibrium concentration of is, 1.0 M

Explanation : Given,

Equilibrium concentration of = 0.26 M

Volume of solution = 1.00 L

Equilibrium constant = 4.0

The balanced equilibrium reaction will be,

The expression of equilibrium constant for the reaction will be:

From the reaction we conclude that the concentration of and are equal.

Let the concentration of be 'X'.

So, concentration of = X

Now put all the values in this expression, we get :

Thus,

The concentration of at equilibrium = X = 1.0 M

The concentration of at equilibrium = X = 1.0 M

you gotta add the following molecules so we can give u an answer

explanation:

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
