\tt Kp=Kc(RT)^{\Delta n}

NH₄Cl (s) ⇔ NH₃ (g) + HCl (g)

Δn = 2 (gas only)

R = 0.082

T = 427 + 273 = 700 K

4.8 = Kc (0.082 x 700)²

Kc = 1.45 x 10⁻³

2. Ultraviolet radiation has a frequency of 6.8 x 10'5Hz. Calculate the energy, in
Gnoma [55]

Answer:

E=4.5\times 10^{-18}\ J

Explanation:

It is given that, the frequency of Ultraviolet radiation is 6.8\times 10^{15}\ Hz

We need to find the energy of the photon. The formula for the energy of a photon is given by :

E=hf\\\\\text{Where h is Planck's constant}\\\\E=6.63\times 10^{-34}\times 6.8\times 10^{15}\\\\E=4.5\times 10^{-18}\ J

So, the energy of the photon is 4.5\times 10^{-18}\ J.
