Question: At a given temperature, the equilibrium constant for reaction <img src="https://cdn.pureessence.tech...

At a given temperature, the equilibrium constant for reaction ⇌ is2.4×10−32.4 \times 10 ^ { - 3 }. At the same temperature, the equilibrium constant for reaction ⇌ is.

A

2.4×10−32.4 \times 10 ^ { - 3 }

B

−2.4×10−3- 2.4 \times 10 ^ { - 3 }

C

4.2×1024.2 \times 10 ^ { 2 }

D

4.8×10−24.8 \times 10 ^ { - 2 }

Answer

4.8×10−24.8 \times 10 ^ { - 2 }

Explanation

Solution

Reaction is reversed. Hence

K=1(2.4×10−3)=4.2×102K = \frac { 1 } { \left( 2.4 \times 10 ^ { - 3 } \right) } = 4.2 \times 10 ^ { 2 }
