Based on the data provided, the total energy of the reaction is 1066 kJ and the reaction is endothermic
<h3>What is the total energy of a reaction?</h3>
The total energy change of a reaction is the difference between the total bond energy of the reactants and the total bond energy of the products.
- If the total change in bond energy is positive, the reaction is endothermic.
- If the total change in bond energy is negative, the reaction is exothermic.
- The total energy change of a reaction = bond energy of reactants - bond energy of products
Bond energy of reactants = 2000 kJ
Bond energy products = 934 kJ
Total energy of reaction = (2000 - 934) kJ = 1066 kJ
The total energy of the reaction is 1066 kJ and the reaction is endothermic.

Answer:
Frequency of photon is 0.513×10¹⁵ s⁻¹
Explanation:
Given data:
Energy of photon = 3.4×10⁻¹⁹ J
Frequency of photon = ?
Planck's constant = 6.63 × 10⁻³⁴ Js
Solution:
Formula:
E = hf
3.4×10⁻¹⁹ J = 6.626 × 10⁻³⁴ Js × f
f = 3.4×10⁻¹⁹ J / 6.626 × 10⁻³⁴ Js
F = 0.513×10¹⁵ s⁻¹
Frequency of photon is 0.513×10¹⁵ s⁻¹.
