Answer: Atoms aren't entirely empty space

Explanation:

Rutherford did his scatter experiment to disprove Thomson's Plum Pudding Model. Rutherford shot helium nuclei at a sheet of gold and expected the particles to all go straight through to a sensor. The reason he expected this was because Thomson said that atoms are mostly made of empty space. Not all the particles went through the gold sheet, a lot of them actually reflected back to him. This meant that atoms aren't entirely empty space and something had to deflect the helium nuclei

A reaction mixture at 175 k initially contains 522 torr of no and 421 torr of o2. at equilibrium, the total pressure in the reac

zzz [600]

The chemical equation would be:

2NO(g) + O2(g) --> 2NO2 (g)

At equilibrium state, the partial pressure of the gases would be as follows : 

NO = 522 - 2x 

O2 = 421 - x 

NO2 = 2x 
- - - - - - - - - - - - -
943 - x = 748 

x = 195

Calculating for Kp,

Kp = (NO2)^2/ ((NO)^2 * (O2)) 

Kp = (2 * 195)^2/ ((522 - 2 * 195)^2 * (421 - 195)) 

Kp = 0.0386

Ne4ueva [31]

Answer:

Rate: R = k [A]²

Explanation:

The rate law equation for a given complex chemical reaction is given as the product of molar concentrations of the reactant raised to the power their respective partial reaction orders. The sum of the partial reaction orders is equal to the overall order of reaction.

For a complex reaction, the rate law is generally determined by the slowest step, which is known as the rate-determining step.

Given reaction mechanism:

Step 1: 2 A⟶ B, slow step

Step 2: B+ C⟶ D, fast step

Overall: 2 A + C ⟶ D

In this given reaction mechanism, the step 1 is the slow step and thus the rate determining step.

Therefore, the rate law for the given mechanism is:

Rate: R = k [A]²

Here, k is the overall rate constant

Also, the overall order of the reaction = 2

Therefore, the given chemical reaction is said to be second order reaction.
