Given the AHºf, calculate the AH°rxn for the formation of diamond from graphite. AHºf (C, graphite)
= 0 kJ/
mol and AHºf (C, diamond) = 2 kJ/mol
0 -2 kJ/mol
o 4 kJ/mol
O +2 kJ/mol
O 0 kJ/mol

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.

The vapor pressure of ethanol is 1.00 × 102 mmhg at 34.90°c. what is its vapor pressure at 61.61°c? (δhvap for ethanol is 39.3 kj/mol.)
