Analyzing +4 | -1

For the following reactions, equilibrium constants are given:

S(s) + {O_2}(g)\underset{{}}{\overset{{}}{\leftrightharpoons}}S{O_2}(g);{K_1} = {10^{52}}

2S(s) + 3{O_2}(g)\leftrightharpoons2S{O_3}(g);{K_2} = {10^{129}}

The equilibrium constant for the reaction,

2SO(g) + {O_2}(g)\leftrightharpoons2S{O_3}(g)

View answer and explanation

Correct option: A

{10^{25}}

The correct answer is A (

{10^{25}}

) because it correctly calculates the equilibrium constant for the target reaction by manipulating the given reactions.
