What is the δg for the following reaction at 25°c?
so3(g) + h2o(l) → h2so4(l)
given:
so3(g): δg= –368 kjper mole
h2o(l): δg= –237 kj per mole
h2so4(l): δg= –689.9 kj per mole
84.9 kj
558.9 kj
–84.9 kj
–558.9 kj

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
