Chapter 1: Problem 18

Consider the following reaction showing photosynthesis: $$\begin{array}{c}{6 \mathrm{CO}_{2}(g)+6 \mathrm{H}_{2} \mathrm{O}(l) \rightarrow \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}(s)+6 \mathrm{O}_{2}(g)} \\ {\Delta H=+2800 \mathrm{kJ} / \mathrm{mol}}\end{array}$$ Which of the following is true regarding the thermal energy in this system? (A) It is transferred from the surroundings to the reaction. (B) It is transferred from the reaction to the surroundings. (C) It is transferred from the reactants to the products. (D) It is transferred from the products to the reactants.

Short Answer

Expert verified
The correct answer is (A) It is transferred from the surroundings to the reaction.

Step by step solution

01

Understanding Endothermic Reactions

In an endothermic reaction, energy or heat is absorbed from the surroundings. In other words, the system (reaction) takes in thermal energy in order for the reaction to proceed. The given reaction is endothermic, as indicated by the positive enthalpy of reaction (\(\Delta H = +2800 \, kJ/mol\)).
02

Applying the Concept

Considering the given options, in an endothermic reaction like the given one, the correct answer would state that the energy transfer takes place from the surroundings to the reaction.
03

Identifying the Correct Option

From the options given, option (A) - 'It is transferred from the surroundings to the reaction' - correctly describes the direction of heat transfer for this endothermic reaction.

Use the following information to answer questions 14-16 The radius of atoms and ions is typically measured in Angstroms \((A),\) which is equivalent to \(1 * 10^{-10} \mathrm{m} .\) Below is a table of information for three different elements. TABLE NOT AVAILABLE Neon has a smaller atomic radius than phosphorus because: (A) Unlike neon, phosphorus has electrons present in its third energy level. (B) Phosphorus has more protons than neon, which increases the repulsive forces in the atom. (C) The electrons in a neon atom are all found in a single energy level. (D) Phosphorus can form anions, while neon is unable to form any ions.
