The reaction represented by following equation was carried out:HCOOCH3 + NaOH → HCOONa + CH3OHWhich graph best shows the relationship between [CH3OH] and time from mixing of the reactants?
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Concentration of product increases and becomes constant after a certain time.The graph of [CH3OH] vs. time would typically show an increase in the concentration of CH3OH over time. At the beginning, the curve might start slowly and then rise more steeply as the reaction proceeds. It would eventually plateau as the reaction approaches completion and the concentration of CH3OH levels off. The specific shape of the curve would depend on the reaction rate and the concentration of reactants.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
