A scientist collected the following data, which show how the pressure of water vapor changes with temperature. Temperature (°C) Pressure (mm Hg) 0 4.5 10 9.6 20 19.1 30 33.2 40 58.7 50 95.6

What would a scientist do to best communicate these data to other scientists in a presentation?

Replace the table with text highlighting pressures.
Change the unit of pressure to atm.
Make a graph for better visual representation.
Display only rows 1, 3, and 6 of the data to simplify results.

explanation:

answer: the enthalpy of the overall chemical reaction is +87.88 kj or +88 kj.

according to hess's law, the overall enthalpy of a reaction is the difference between the sum of enthalpy values of all the products and the sum of enthalpy values of all the reactants.

δh(reaction) = ∑nδh(products) - ∑nδh(reactants)

δh(reaction) = [δh +δh] - [δh]

δh(reaction) = [1(-287.02) + 1(0) ] - [1(-374.9)] kj = +87.88 kj

here, δh (pcl3) = -287.02 kj, δh(cl2) = 0, δh(pcl5) = -374.9 kj

therefore, enthalpy of the overall reaction is +87.88 kj or +88 kj.
