Which equation or rule can be used to estimate the pseudo-critical properties of mixtures based on the pure-component critical c

sveticcg [70]

Answer:

c. Kay's rule

Explanation:

Kay's rule -

The rule is used to determine the pseudo reduced critical parameters of mixture , with the help of using the critical properties of the components of a given mixture .

The equation for Kay's rule is as follows ,

PV = Z RT

Where Z = The compressibility factor of the mixture .

Hence from the given options , the correct answer is Kay's rule .

Which too factors determine whether a collision between two reactant molecules will result in a reaction? select all that apply.

stepan [7]

Answer:

The particles must be in the correct orientation upon impact.

The particles must collide with enough energy to meet the activation energy of the reaction.

Explanation:

This a problem related to chemical kinetics. The collision theory is one of the theories of reaction rates and it perfectly explains how the effectiveness of colliding molecules dictates the pace of a reaction.

For reactions to occur, there must be collisions between reacting particles. It implies that the collision per unit time and how successful collisions are determines the rate of chemical reactions in most cases. Therefore, for a collision to be successful, colliding particle must have enough energy which is greater than the activation energy of the reaction. In order to also produce the desired products, the colliding particles must be properly oriented.

Which of the following ratios are needed to determine the mass of oxygen produced from the decomposition of 10 grams of potassiu

Zielflug [23.3K]

The ratios which are needed to determine the mass of oxygen produced from the decomposition of 10 grams of potassium chlorate are;

31.998 g O2 : 1 mole O2
3 mole O2 : 2 mole KClO3
112.55 g KClO31 mole KClO3

From stoichiometry;

We can conclude that according to the reaction;

3 moles of oxygen requires 2 moles of KClO3 to be produced.

And from molar mass analysis;

31.998 g O2 is equivalent to 1 mole O2
O2112.55 g KClO3 is equivalent to 1 mole KClO3

Why solids do not undergo diffusion

babunello [35]

Answer:

Solids do not undergo diffusion because it has a fixed structure (vibrates in a fixed position) and it also cannot be compressed.

Hoped this helped in any way

Have a nice day
