What is δs° for the reaction so3(g) + h2o(l) → h2so4(aq)? substance s°(j/k • mol) so3(g) 256.2 h2o(l) 69.9 h2so4(aq) 156.9

Answer : The value of for the reaction is, -169.2 J/K

Explanation :

The given balanced reaction is,

The expression used for entropy change of reaction is:

where,

= entropy change of reaction = ?

n = number of moles

= standard entropy of formation

= 156.9 J/mol.K

= 256.2 J/mol.K

= 69.9 J/mol.K

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

Therefore, the value of for the reaction is, -169.2 J/K

its mg hope this

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
