Answer 4

sugar solutions is

Answer 5

Consider the reaction.

At equilibrium, the concentrations of the different species are as follows.

[NH3] = 0.105 M
[N2] = 1.1 M
[H2] = 1.50 M

What is the equilibrium constant for the reaction at this temperature?

Answer 6

K=0.105*0.105/1.1*1.50*1.50*1.50
=0.011025/3.7125
=0.002959

Answer 7
