(i) 2Fe²? + H? O? → 2Fe³? + 2OH?
(ii) 2MnO? + 5H? O? + 6H? → 2Mn²? + 5O? + 8H? O
So sum of (x + y + x¹ + y¹ + z¹) = 2 + 2 + 2 + 5 + 8 = 19

k = Ae? Ea/RT
ln (K? /K? ) = (Ea/R) [1/T? - 1/T? ]
ln (5) = (Ea/8.314) [1/300 - 1/315]
1.6094 = (Ea/8.314) [15 / (300 × 315)]
Ea = 84297 J

Pext is zero so W = zero

For hydrogen atom :
For Lyman series n? = 1 & n? = ∞
1/λH = RH [1/1² - 1/∞²] So, λ = 1/RH
For He? ion Balmer series n? = 2 & n? = 3
1/λHe? = RH × Z² [1/n? ² - 1/n? ²]
1/λHe? = RH × 4 × [1/4 - 1/9] = RH × 4 × (5/36)
1/λHe? = (5/9)RH = (5/9) (1/λ)
(λHe? ) = (9/5)λ

XeF? + SbF? → [XeF? ]? [SbF? ]?
