Question

what is the value of (delta) ng for the following reaction :- co(g) + cl2(g)= cocl2(g)

Answer 1

(Del) ng = gaseous molecule of product - gaseous molecule of reactant
in given equation gaseous molecule of reactant is 2
and the gaseous molecule of product is 1
(Del) ng = 1-2 = -1

Answer 2

The value of Δng for reaction $CO + Cl_2\rightarrow COCl_2$ is -1.

Given:

The reaction involved: $CO + Cl_2\rightarrow COCl_2$

To find:

Δng = ?

Formula to be used:

Δng = $(n_p-n_r)_g$

Where,

$n_p$ - Number of moles of product

$n_r$ - Number of moles of reactants.

Calculation:

The given equation is:

$CO + Cl_2\rightarrow COCl_2$

As per the given equation, the number of molecules of reactants and products involved in the reaction is as follows:

Reactants:

CO - 1

$Cl_2$ - 1

Product:

$COCl_2$ - 1

We know that

Δng = $(n_p-n_r)_g$

Δng = ( 1 - (1 + 1)$)_g$

Δng = ( 1 - 2)

Δng = - 1

Conclusion:

From the above calculation it is inferred that Δng value for the given reaction is -1.
