Catalysis increase the rate of reaction by

1 answer:

5 0

Catalysis increases the rate of the reaction, by lowering or decreasing the activation energy of the said reaction, the minimum amount of energy to essentially get the reaction started, and have the reactant molecules to react with each other to produce the final products.

The number of electrons present in 4.2 gram of methane is

jeka94

Answer:

Explanation:

One CH4 molecules = 10 electrons ( Carbon 6e + 4Hydrogen 4e)

A mole of any substance witll have = 6.023*10^23 atom/ molecuels,

One mole of any substnce is equal is nothing but its moalr mass

Molar mass of CH4 = 16.04

It mean,

16.04 g of CH4 has = 6.023*10^23 molecules of methane

but

4.2 gram of CH4 = 6.023*10^23 * 4.2 /16.04 = 1.58*10^23 molecuels of CH4

So one molecule has =10 electrons

1.58*10^23 molecuels will have = 1.58*10^23 * 10 = 1.58*10^24

Hope this help you

At a particular temperature, the solubility of He in water is 0.060 M when the partial pressure is 0.90 atm. 2.27 atm is the partial pressure of Kr would give a solubility of 0.150 M.

<h3>What is Henry's Law ?</h3>

According to Henry's law, the weight of a gas dissolved by a liquid is proportional to the pressure of the gas onto the liquid.
With very few exceptions, a solute molecule in an extremely diluted solution will only have solvent molecules as its close neighbors. This means that the likelihood that a specific solute molecule will escape into the gas phase is predicted to be independent of the total concentration of solute molecules.

Solution:

The solubility of gas is directly proportional to partial pressure. It is expressed as:

S = $K_ h \times P _g_a_s$

where, S = Solubility of gas

$K_h$ = Henry's Law constant

$P_g_a_s$ = Partial pressure of gas

Now, put the values in above expression we get

0.060M = $K_h$ × 0.9 atm

$K_h$ = = 0.066 M/atm

Now we have to find the partial pressure of He

0.150 M = 0.066 M/atm × $P_g_a_s$

$P_g_a_s$ = 2.27 atm
