C I’m pretty sure. The first step is the rate determining step
Answer:
![C_{rms}=465.76\ m/s](https://tex.z-dn.net/?f=C_%7Brms%7D%3D465.76%5C%20m%2Fs)
Explanation:
The expression for the root mean square speed is:
R is Gas constant having value = 8.314 J / K mol
M is the molar mass of gas
Molar mass of
= 0.04599 kg/mol
Temperature = 400 K
Thus,
![C_{rms}=465.76\ m/s](https://tex.z-dn.net/?f=C_%7Brms%7D%3D465.76%5C%20m%2Fs)
<em>Kinetic molecular Theory points:</em>
1. Gases molecules are always in random motion.
2. Gases molecule collide with each other and with the walls of container.
3. Gases molecules total volume is negligible as compare to container.
4. There is no attractive forces between the gases particles
5. K.E is directly proportional to absolute temperature.
<em>Why liquid are denser than gases according to K.M.T:</em>
1. As gases are in random motion, so they have weak forces/ no attractive forces (Acc. to KMT) due to this they are apart as compare to liquid which have stronger forces are closer to each other. So volume of gases will be greater. d= m/v
2. K. E of gases are greater than liquid due to this gases move randomly, apart from each another. Due to this their volume will be greater. d= m/v
3. Gases molecules total volume is negligible as compare to container which show that gases molecules have large spaces between them which causes lower in density.
Answer:
HF is the Arrhenius acid and KOH is the Arrhenius base.
Explanation:
An Arrhenius acid dissociates in water to form H+ ions in solution.
An Arrhenius base dissociates in water to form OH- ions in solution.
Write the equations by breaking the compounds into their elements
HF→ H⁺ + F⁻ HF produces H⁺ when added to water, so it is the acid.
KOH→ K⁺ + OH⁻ KOH produces OH⁻ when added to water, so it is the base.
