Given the equilibrium constants for the following two reactions in aqueous solution at 25 ∘c hno2(aq)h2so3(aq)⇌⇌h+(aq) + no2−(aq)2h+(aq) + so32−(aq)kc = 4.5 × 10−4kc = 1.1 × 10−9 what is the value of kc for the reaction 2hno2(aq) + so32−(aq)⇌h2so3(aq) + 2no2−(aq)

Answer : The value of for the final reaction is, 184.09

Explanation :

The equilibrium reactions in aqueous solution are :

(1)        

(2)        

The final equilibrium reaction is :

Now we have to calculate the value of for the final reaction.

Now equation 1 is multiply by 2 and reverse the equation 2, we get the value of final equilibrium reaction and the expression of final equilibrium constant is:

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

Therefore, the value of for the final reaction is, 184.09

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the answer is symmetrical : )
