Help!! Write the equilibrium constant for the following equation:

SO3(G) + H2O(g) <--> H2SO4(I)

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

im not exactly sure but i think its b!

a electronegativity decreases beacuse the size of nucleus is bigger.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
