Drag each quantity to the correct location on the table. Complete the table of bond energies and bond lengths. 125 pm 145 pm 167

stiv31 [10]

Answer: N-N: 145 pm and 167 KJ/mol

N=N: 125 pm, 418 KJ/mol

And N2: 110 pm , 942 KJ/mol

Explanation: Bond length is inversily proportional to bond energy.

Greater the bond length , smaller the bond energy and vice-versa.

In the coal-gasification process, carbon monoxide is converted to carbon dioxide via the following reaction: CO (g) H2O (g) CO2

jolli1 [7]

Answer: $K_{eq}$ at the temperature of the experiment is 0.56.

Explanation:

Moles of $CO$ = 0.35 mole

Moles of $H_2O$ = 0.40 mole

Volume of solution = 1.00 L

Initial concentration of $CO$ = $\frac{0.35mol}{1.00L}=0.35M$

Initial concentration of $H_2O$ = $\frac{0.40mol}{1.00L}=0.40M$

Equilibrium concentration of $CO$ = $\frac{0.19mol}{1.00L}=0.19M$

The given balanced equilibrium reaction is,

$CO(g)+H_2O(g)\rightleftharpoons CO_2(g)+H_2(g)$

Initial conc. 0.35 M 0.40 M 0 M 0M

At eqm. conc. (0.35-x) M (0.40-x) M (x) M (x) M

Given: (0.35-x) = 0.19

x= 0.16 M

The expression for equilibrium constant for this reaction will be,

$K_{eq}=\frac{[CO_2]\times [H_2]}{[CO]\times [H_2O]}$

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

$K_{eq}=\frac{0.16\times 0.16}{(0.35-0.16)\times (0.40-0.16)}$

$K_{eq}=\frac{0.16\times 0.16}{(0.19)\times (0.24)}=0.56$

Thus $K_{eq}$ at the temperature of the experiment is 0.56.
