Answer:
The correct answer to the following question will be "4.08 × 10⁻¹⁹ Joule".
Explanation:
Given:
Wavelength, λ = 486.0 nm
As we know,

On putting the estimated values, we get
⇒ 
⇒ 
∴ 1 ev = 1.6 × 10⁻¹⁹ J
Now,
Energy, 
⇒ 
In acidic solutions you have H+ but in basic solutions you have OH-.
You need know that for to balance the reaction.
Reactant A must be second order and reactant B first order. Overall = add them so 3rd order.
A. true
b. false
c. true
d. false
e. false
