The statement which best described the effect of color on energy absorption and reflection is this: LIGHT COLORS REFLECT MORE AND ABSORB LESS THAN DARK COLORS. Black color absorbs all incident radiations while white color reflects all incident radiations; all other colors fall in the midst of these two colors.

scoray [572]

Answer:

<u>d) 1.8 atm</u>

Explanation:

<u>According to Boyle's Law,</u>

  • P₁/T₁ = P₂/T₂

Here, we are given :

  1. <u>P₁ = 1.5 atm</u>
  2. <u>T₁ = 25°C = 298 K</u>
  3. <u>T₂ = 75°C = 348 K</u>

<u />

<u>Solving</u>

  • P₂ = P₁T₂/T₁
  • P₂ = 1.5 x 348 / 298
  • P₂ = 522/298
  • P₂ = <u>1.8 atm</u> (approximately)

The reaction for the formation of phosgene from carbon monoxide and chlorineCO + Cl2 --&gt; COCl2 is first order in CO and secon
Ilya [14]

Answer:

r = k . [CO] .[Cl_{2}]

Explanation:

Let´s consider the following reaction:

CO + Cl₂ ⇒ COCl₂

The general rate law is:

r = k . [CO]^{m}. [Cl_{2}]^{n}

where,

r is the rate of the reaction

k is the rate constant

[CO] and [Cl₂] are the molar concentrations of each reactant

m and n are the reaction orders for each reactant

Since the reaction is first order in CO, m = 1. The overall order is the sum of all the individual orders. In this case, the overall order m + n = 2. Then,

m + n = 2

n = 2 - m = 2 - 1 = 1

The reaction is first order in Cl₂.

The rate law is:

r = k . [CO]. [Cl_{2}]
