Q17.43P - Chemistry: Molecular Nature Of Matter And Change

Question

Gaseous decomposes according to the reaction 

${\mathbf{PCI}}_{\mathbf{5}\mathbf{\left(}\mathbf{g}\mathbf{\right)}}\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{\square }\mathbf{ }\mathbf{ }\mathbf{ }{\mathbf{PCI}}_{\mathbf{3}\mathbf{\left(}\mathbf{g}\mathbf{\right)}}\mathbf{+}{\mathbf{CI}}_{\mathbf{2}\mathbf{\left(}\mathbf{g}\mathbf{\right)}}$

In one experiment, 0.15 mol of ${\mathbf{PCI}}_{\mathbf{5}\mathbf{\left(}\mathbf{g}\mathbf{\right)}}$ was introduced into a 2.0-L container.

Construct the reaction table for this process.

Step-by-Step Solution

Answer

     The construction of the reaction table is as follows

Step 1: what is reaction table

The reaction table is a spreadsheet format that contains all numerical and algebraic data relevant to the problem and allows for developing a consistent set of analytical and computational procedures inside a single calculational framework. We can use the approach to detect common ideas, evaluate issues, arrange computations, make logical conclusions, identify distracters, validate results, and move forward with confidence and precision to a solution.

Step 2: Construction of reaction table

  Rewrite the reaction as follows:

 ${\mathrm{PCI}}_{5\left(\mathrm{g}\right)} \square {\mathrm{PCI}}_{3\left(\mathrm{g}\right)}+{\mathrm{CI}}_{2\left(\mathrm{g}\right)}$

  The number of moles of is 0.15 mol, and the volume of the flask is 2.0 L.

 $\left[{\mathrm{PCI}}_5\right]=\frac{0.15}{2}$

   The construction of the reaction table is as follows
