The answer is B because the more ions the more electrolytes it has
Here are some rules:
1. The oxidation state of a free element (uncombined element) is zero.2. For a simple (monatomic) ion, the oxidation state is equal to the net charge on the ion.3. Hydrogen has an oxidation state of +1 and oxygen has an oxidation state of −2 when they are present in most compounds.
The oxidation number of Fe in Fe(NO3)2 is +3.
From the equation of the graph, the activation energy of the reaction is -2.2 * 10⁴ J/mol.
<h3>What is activation energy?</h3>
Activation energy is the minimum required energy that reactant molecules must possess for a reaction to proceed towards formation of products.
The activation energy is determined from the slope of ln k against 1/T(K).
Given the equation, y = -2.2 * 10⁴ x + 45.0.
Comparing with the equation of a straight line, y = mx + c
The gradient, m = -2.2 * 10⁴
Therefore, the activation energy of the reaction is -2.2 * 10⁴ J/mol.
In conclusion, reactant molecules must break the activation energy barrier in order to form products.
