Consider the reaction

2 NO2 (g) <=> N2O4 are 0.2 M, what is the value of Kc?

A. 0.2
B. 0.3
C. 0.225
D. 5.0
E. 2.5
Please help.

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

wher is the rest of the question

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
