The partial pressure of CH3OH (g), CO(g) and H2(g) in equilibrium mixture for the reaction

CO(g) + 2H2(g) ----> CH3OH(g)

are 2.0, 1.0, and 0.1 atm respectively at 427°C. The value of Kp for decomposition of CH3OH to CO and H2 is

A particle moves with simple harmonic motion in a straight line. In first τ s, after starting from rest it

travels a distance a, and in next τ s it travels 2a, in same direction, then :

(1) amplitude of motion is 4a

(2) time period of oscillations is 6τ

(3) amplitude of motion is 3a

(4) time period of oscillations is 8τ
