Question

For the following reaction:

$\mathrm { NO } _ { ( \mathrm { g } ) } + \mathrm { O } _ { 3 ( \mathrm {~g} ) }$ $\mathrm { NO } _ { 2 ( \mathrm {~g} ) } + \mathrm { O } _ { 2 ( \mathrm {~g} ) }$

The value of $\mathrm { K } _ { \mathrm { c } }$ is $8.2 \times 10 ^ { 4 }$ what will be the value of $\mathrm { K } _ { \mathrm { c } }$ for the reverse reaction?

• A. $8.2 \times 10 ^ { 4 }$
• B. $\frac { 1 } { 8.2 \times 10 ^ { 4 } }$
• C. $\left( 8.2 \times 10 ^ { 4 } \right) ^ { 2 }$
• D. $\sqrt { 8.2 \times 10 ^ { 4 } }$

Answer 1

Answer: (B)

$\frac { 1 } { 8.2 \times 10 ^ { 4 } }$

Answer 2

: The value of for the reverse reaction will be

$\frac { 1 } { 8.2 \times 10 ^ { 4 } }$.
