Which is an overall third-order reaction? a. R=k[A]2[b]

b. R= k[A][B]1

c. R=k [X]2[Y]3

d. R=k [x][y]

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
