The system described by the reaction co(g)+cl2(g)⇌cocl2(g) is at equilibrium at a given temperature when pco= 0.26 atm , pcl2= 0.15 atm , and pcocl2= 0.66 atm . an additional pressure of cl2(g)= 0.39 atm is added. find the pressure of co when the system returns to equilibrium.

The new pressure of CO is 0.09 atm

Explanation:

For the given chemical reaction:

The expression of for above equation follows:

            .......(1)

We are given:

Putting values in above equation, we get:

Addition pressure of chlorine added = 0.39 atm

Now, the equilibrium is re-established:

Initial:            0.26     0.15             0.66

At eqllm:     0.26-x   0.54            0.66+x

Putting values in expression 1, we get:

So, new pressure of CO = 0.26 - x = (0.26 - 0.17) = 0.09 atm

Hence, the new pressure of CO is 0.09 atm

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
