If electricity cannot be destroyed or created then why do we got to pay for electricity?

icang [17]

Energy cannot be destroyed or created. Electricity is a form of energy which has to be created from other forms of energy. We have to pay for the creation of electricity because it requires certain resources to transform other energies into electricity.

Answer:

The rate equation for this reaction:

$R=k[NH_3]^0$

Explanation:

Decomposition of ammonia:

$2NH_3\rightarrow N_2+3H_2$

Rate law of the can be written as;

$R=k[NH_3]^x$

1) Rate of the reaction , when $[NH_3]=2.0\times 10^{-3} M$

$1.5\times 10^{-6} M/s=k[2.0\times 10^{-3} M]^x$ ..[1]

2) Rate of the reaction , when $[NH_3]=4.0\times 10^{-3} M$

$1.5\times 10^{-6} M/s=k[4.0\times 10^{-3} M]^x$ ..[2]

[1] ÷ [2]

$\frac{1.5\times 10^{-6}M/s}{1.5\times 10^{-6}M/s}=\frac{k[2.0\times 10^{-3}M]^x}{k[4.0\times 10^{-3}M]^x}$

On solving for x , we get ;

x = 0

The rate equation for this reaction:

$R=k[NH_3]^0$
