Which of the following is not true for an exothermic reaction?

Chemistry
1 answer:
Gennadij [26K]3 years ago
4 0

Answer:

The false statement regarding an exothermic reaction is: <em>A.</em><em> the products have a higher enthalpy than reactants</em>

Explanation:

An exothermic reaction is a type of chemical reaction that involves the <u>release of energy from the </u><em><u>system to the surroundings</u></em>. Thus <em>increasing the temperature of the surroundings.</em>

In this reaction, the <em>enthalpy or energy of the reactants is greater than the enthalpy or energy of the products</em>.<em> </em>(\Delta H_{f} (Products) < \Delta H_{f} (reactants))

<u>As the enthalpy change of a reaction</u>: \Delta H_{r} = \sum \Delta H_{f} (Products) - \sum \Delta H_{f} (reactants)

Therefore, the <em>enthalpy change for an exothermic reaction is negative</em> (\Delta H_{r} < 0)

Identify the oxidizing and reducing agents in the following: H2S(aq) + Cl2(g) -&gt; S(s) + 2HCI (aq)
alexgriva [62]

The oxidizing and reducing agent in the above redox reaction are hydrogen sulphide (H2S) and Chlorine (Cl) respectively.

<h3>What is an oxidizing and reducing agent?</h3>

An oxidizing agent is any substance that oxidizes, or receives electrons from another substance and as a result, becoming reduced.

On the other hand, a reducing agent is any substance that reduces or donates electrons to another and as a result becomes oxidized.

According to this reaction; H2S(aq) + Cl2(g) -> S(s) + 2HCI (aq)

  • H2S accepts electrons from Cl2 and becomes reduced to S
  • Cl2 donates electrons to H2S and becomes oxidized to HCl

Therefore, the oxidizing and reducing agent in the above redox reaction are hydrogen sulphide (H2S) and Chlorine (Cl) respectively.

Archy [21]

<u>Answer:</u>

<em>The system is the Answer </em>

<em></em>

<u>Explanation:</u>

System is the region which is taken into consideration.

While we perform a chemical reaction the system is the substance taken in the container.

So, A thermodynamic system is the amount of matter or the region in universe which is under the study.

The region outside the beaker are called as surroundings.

The beaker (the surface which separates the system from its surroundings) is said to be the boundary

System + surroundings = universe
