Chapter 10.3, Problem 10.23QAP

Use Le Ch?telier’s principle to predict whether each of the following changes causes
the system to shift in the direction of products or reactants:

HCHO2(aq) + H2O(l) CHO2- (aq) + H3O+ (aq)

  1. adding more CHO2- (aq)
  2. removing some HCHO2 (aq)
  3. removing some H3O+ (aq)
  4. adding more HCHO2 (aq)

Students have asked these similar questions
Le Chatelier's Principle Determine the direction to which the equilibrium will shift if the following changes occur (forward or reverse direction) CH₂COOH(aq) H*(aq) + CH₂COO¯(aq) * sodium acetate is added * additional acetic acid is added * sodium hydroxide is added
For each of the following reactions, tell whether the equilibrium will favor the reactants or the products.  Use the Ka values in the picture. a. HNCO(aq) +  CN– (aq)  ⇄⇄ NCO– (aq)  +  HCN (aq) b. HCO2H (aq) +  OH– (aq)  ⇄⇄  CO2H– (aq)  +  H2O (l)
Look at the following reaction: HCO3- (aq) + HCl (aq) ⇌ H2CO3 (aq) + Cl- (aq) Which of the following options is correct?   Question 7 options:   Reaction will proceed to the reactants because HCl (aq) is weaker   Reaction will proceed to the products because H2CO3 (aq) is stronger   Reaction will proceed to the products because H2CO3 (aq) is weaker   Reaction will proceed to the reactants because HCl (aq) is stonger
