Why nitrogen is less reactive at room temperature

K@Łp@N@ $Øđh!?? 6 years, 9 months ago

The nitrogen atom is very small in size,therfore the bond lenght is also quite small and as a result the bond dissociation energy is quite high. This reason leads N2 to be very less reactive at room temperature

1Thank You

Yogita Ingle 6 years, 9 months ago

Dinitrogen (N₂) IS formed by sharing three electron pairs between two nitrogen atoms.The two nitrogen atoms are joined by triple bond(N ≡ N). The nitrogen atom is very small in size ,therefore the bond length is also quite small(109.8 pm) & as a result the bond dissociation energy is quite high(946Kj / mol).This reason leads N₂ to be very less reactive at room temperature.

A first order reaction is 50% complete in 25min. Calculate the time for 80% completion of the reaction

Posted by Piyush Chourasia 6 years, 9 months ago

CBSE > Class 12 > Chemistry

1 answers

Sia ? 6 years, 9 months ago

We know that,
{tex}log(\frac{N}{N_\circ})=\frac{t}{t_\frac{1}{2}}\times log(\frac{1}{2}){/tex}
N = amount left after decay = 100 - 80 = 20
N_o= initial amount = 100
t = time for 80% completion reaction
half life = 25 minutes
Substitute all values in formula, we get
{tex}log(\frac{20}{100})=\frac{t}{25}\times log(\frac{1}{2})\\t=58 \ min.{/tex}

In zno, zn2+ ions occupy the interstitial sites and electrons are trapped in the interstitial sites for the neutralization. Crystals that shows such type of defects are generally colored. Zinc oxide is White in color but on heating it turns into yellow because on heating is losses oxygen reversibly at high temperature.
