For the following graphs,


Choose from the options given below, the correct one regarding order of reaction is :

Isotope(s) of hydrogen which emits low energy $$\beta$$^$$-$$ particles with t_1/2 value > 12 years is/are

Given below are two statements :

Statement I : The pH of rain water is normally $$-$$ 5.6.

Statement II : If the pH of rain water drops below 5.6, it is called acid rain.

In the light of the above statements, choose the correct answer from the options given below :

The value of K_C is 64 at 800 K for the reaction

N₂(g) + 3H₂(g) ⇌ 2NH₃(g)

The value of K_C for the following reaction is :

NH₃(g) ⇌ $${1 \over 2}$$N₂(g) + $${3 \over 2}$$H₂(g)
