I’m not sure what this says could you translate it to English please?
Answer:
See below
Step-by-step explanation:
An exothermic reaction tends to occur spontaneously because the products are more stable than the reactants.
Nature tries to get to the lowest energy state.
2.a solute and a solvent is your answer
Answer:
The answers are in the explanation
Explanation:
A. For the reaction:
CO(g) + H₂O(g) ⇌ CO₂(g) + H₂(g); ΔH°=−41kJ.
As the reaction is exothermic ( ΔH°<0), you need to use low temperature to increase the equilibrium yield of hydrogen -LeChatelier's principle-.
We would use <em>low </em>temperature. For an <em>exothermic </em>reaction such as this, <em>decreasing </em>temperature increases the value of K and the amount of products at equilibrium.
B.
c. No. We cannot increase the equilibrium yield of hydrogen by controlling the pressure of this reaction.
It is possible to increase the equilibrium yield of reaction by controlling the amount of reactants added. As reactants and products are gases, the pressure of the reaction will not change the amount of reactants or products in the equilibrium.
I hope it helps!
Answer:
5.77% Error.
Explanation:
Given an experimental value of 275 g , and a theoretical value of 260 g, the percent error can be found using the equation:
% Error = ( | 260 - 275 | / 260 ) × 100 = ( | - 15 | / 260 ) × 100 = ( 15 / 260 ) × 100 = 1500/260 = 300 / 52 = 5.769230769230.. ≈ 5.77%
