Choose all of the processes from below which describe changes
which are independent of the path by which the
change occurs.
a. the elevation increase experienced by a traveller travelling
from Grand Isle, LA to Denver, Colorado
b. the amount of work required to build a house
c. the distance travelled by a steer in a rodeo attempting to evade
capture
d. the work generated by a homogeneous gaseous chemical reaction
carried out inside of a bomb calorimeter
e. the longitude decrease experienced by a traveller travelling
from Baton Rouge, LA to London, England
f. the kinetic energy aquired by a bullet as it reaches a specific
speed
g. kinetic energy lost by an automobile after crashing into a tree
and stopping
Change in state functions are independent of the path followed to attain that state .
(a)the elevation increases experienced by a traveller .....(independent)
(elevation of final minus the initial place remains constant )
(b) the amount of work to built a house ...(dependent )
( work is a path function )
(c) the distance travelled by a steer .....(dependent)
(d) the work generated by homogeneous gaseous chemical reaction carried out in bomb calorimeter . ...(independent)
(because it is equivalent to ∆U)
(e) the longitude decreases experienced by a traveller ...(independent )
(f)kinetic energy acquired by a bullet as it reaches a specified speed ....(independent )
(g) kinetic energy lost by an automobile after crashing into a tree and stopping .. (independent)
Kinetic energy lost or gained depends on the initial and final speed only .

Part 1.) Select all of the correct statements about reaction rates from the choices below. 1. The lower the rate of a reaction the longer it takes to reach completion. 2. As a reaction progresses its rate goes up. 3. Catalysts decrease reaction rates. 4. A balanced chemical reaction is necessary to relate the rate of reaction to the concentration of a reactant. 5. Reaction rates increase as concentrations of homogeneous catalysts increase. 6. The higher the rate of a...
