Natasha2012 [34]

Answer:

<h2>13.82 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question we have

density =  \frac{698}{50.5}  \\  = 13.8217...

We have the final answer as

<h3>13.82 g/mL</h3>

Hope this helps you

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}]
