Question

when 1.00 mol co and 3.00 mol h2 are placed into a 10.0 l vessel at 9270c and allowed to come to equilibrium, the mixture is found to contain .387 mol h2o at equilibrium. what is the concentration of each substance at equilibrium? what is the kc for this reaction at 9270c?

Answer 1

The largest value of w (in N)that they can support as shown in equilibrium.

What is equilibrium?

a State of balance between opposing forces or actions that is either static as in nobody acted on by forces whose resultant is zero or dynamic reaction when the rates of reaction in both differentions are equal.

Sol- the total force in x direction is given as,

€Fx=0

T1 sin 37°=T2 sin 53°

100×3/5 =T/2 ×4/5

T2=75 N

The given total force is-

€Fy=0

T1 cos 37°=T2 cos 53°+W

W=80×4/5 -75×3/5

W=19N

Thus

The largest value of W is 19N.
