Would changing the volume of the original stock solution and the incremental dilution volumes to a new constant value effect the successive concentrations. say by starting with 10 ml and transferring 10 ml increments? if you say yes, repeat the above with 10 ml increments and explain.

sry but any answer choices

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
