Aerosol cans have a label that warns the user not to use them above a certain temperature and not to dispose of them by incinera
Alex73 [517]

Answer:

1.40 atm

Explanation:

To answer this question we can use<em> Gay-Lussac's law</em>, which states:

  • P₁T₂=P₂T₁

When volume and number of moles remain constant.

  • P₁ = 1.11 atm
  • T₁ = 23°C ⇒ 23+273.16 = 296.16 K
  • T₂ = Boiling point of water = 100 °C ⇒ 100+273.16 = 373.16 K
  • P₂ = ?

We <u>put the known data in the equation and solve for P₂</u>:

  • 1.11 atm * 373.16 K = P₂ * 296.16 K
  • P₂ = 1.40 atm

The proposed mechanism for a reaction is: Step 1: A + B X (fast) Step 2: X + C Y (slow) Step 3: Y D (fast) What is the overall r
PolarNik [594]

Answer:

(slow)xy2+z→xy2z (fast) c step1:step2:xy2+z2→xy2z2

Explanation:

Step1: xy2+z2→xy2z2 (slow)

Step2: xy2z2→xy2z+z (fast)

2XY 2 + Z 2 → 2XY 2 Z

Rate= k[xy2][z2]

 

When the two elementary steps are summed up, the result is equivalent to the stoichiometric equation. Hence, this mechanism is acceptable. The order of both elementary steps is 2, which is ‘≤3’; this also makes this mechanism acceptable. Furthermore, the rate equation aligns with the experimentally determined rate equation, and this also makes this mechanism acceptable. Therefore, since all the three rules have been observed, this mechanism is possible.
