The rate of disappearance of hbr in the gas phase reaction 2hbr(g)→h2(g)+br2(g) is 0.140 m s-1 at 150°c. the rate of appearance
VMariaS [17]
<span>Answer: 0.070 m/s

Explanation:

1) balanced chemical equation:

given: 2HBr(g) → H2 (g)+Br2(g)

2) Mole ratios:

2 mol HBr : 1 mol H2

3) That means that every time  2 moles of HBr disappear 1 mol of H2 appears.

That is, the H2 appears at half rate than the HBr disappears.

∴ rate of appearance of H2 = rate of disappearance of HBr / 2 = 0.140 m/s / 2 =  0.070 m/s, which is the answer.</span>

Match the theoretical motions of particles with their associated phases. Solid, Gas, Liquid. 1. oscillation about a fixed point
viktelen [127]
The correct combination of <span>theoretical motions of particles with their associated phases is given below:

1) Solid : </span>oscillation about a fixed point . Because solids do vibrate (atoms/molecules of a solid oscillate around their mean positions)<span>
2) Gas : </span>translation, vibration, rotation. The gas molecules are free to rotate, oscillate & vibrate. <span>
3) Liquid: </span>rotation and vibration. The liquid molecules are free to rotate & vibrate.
