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?

You are wrong and ans. is 2

Please reply.......................................

The molar mass of N₂O as well as CO₂ is 44g/mol. At 298k and 1 atm, N₂O contains n molecules of gas.What is the number of molecules in 2.0 L of CO₂ under same conditions?

If e^sinX-e^-sinX=4 then find the number of real solutions?

sin(e^X)=2^X+2^-x then find the number of real solutions?

Is arihant maths books accompanys to changing pattern of IIT exams

can u please tell me that from which book(any guesses) this question belongs.as my teacher wants to know that.

Thanking u

A hyperbola having the transverse axis of length 2sin

,is confocal with the ellipse 3X²+4Y²=12,Then what will be its equation?

Please explain clearly.

Let ABCD be a quadilateral with area 18, with side AB parallel to the side CD and AB=2CD.Let AD be perpendicular to AB and CD.If a circle is drawn inside the quadilateral ABCD touching all the sides ,Then what is its radius.
