The answer is d. Please explain

When pressure is applied to the wquilibrium system ice(s)-----H₂O(l), Which of

the following will happen?

1.More ice will be formed.

2.water will evaporate.

3.more water will be formed.

4.equilibrium will not be reached.

Thank u ,dost

For the reaction H₂(g) + I₂(g)------2HI(g)

The equilibrium constant K_p depends on the

(a)Total pressure (b)Catalyst used.

(c)Amount of H₂ and I₂. (d) Temperature.

The equilibrium constant for the reaction

CO(g)+H₂O(g)-----CO₂(g)+H₂(g) is 4 at 1000 K.When equimolar mixtures of CO and H₂O are heated to 1000 K,Calculate the percentage of CO₂ formed at equilibrium?

Represent the following families of curves by forming the corresponding differential equation, where a and b are parameters.

y=ae^3x+be^5x.

For all

in interval 0,

/2, show thwt cos(sin

) > sin(cos

).

Two small balls A and B , each of mass m, are joined rigidly by a light horizontal rod of length L.The rod is clamped at the center in such a way that it can rotate freely about a vertical axis through its center. The system is rotated with an angular speed w about the axis. A particle P of mass m kept at rest sticks to the ball A as the ball collides with it. Find the new angular speed of the rod?
