Answer: The equilibrium constant for the reaction at 25 °C is 346.7
Explanation:
Formula used :
where,
= standard Gibb's free energy change = -14.50kJ/mol =14500 J/mol
R = universal gas constant = 8.314 J/K/mole
T = temperature = 
= equilibrium constant = ?
Putting in the values we get:
The equilibrium constant for the reaction at 25 °C is 346.7
A. 2
trust me i used to so this in middle school
4 is correct. Since gases are made of rapidly moving molecules with a relatively high amount of kinetic energy, the molecules have a hard time coming together to form a liquid. You must lower their kinetic energy with a low temperature and force the molecules together with high pressure.
The answer should be (D) endothermic reaction.
Reason : - Reactions in which energy is absorbed are called endothermic reactions. In your provided question, 150 kcal energy is being <u>absorbed</u>, and thus, we can say that it is an endothermic reaction.
Answer:
47900 cm
General Formulas and Concepts:
<u>Chemistry</u>
- Base 10 Decimal System
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
0.479 km
<u>Step 2: Identify Conversions</u>
1 km = 1000 m
1 m = 100 cm
<u>Step 3: Convert</u>
