[References] The rate of disappearance of HCl was measured for the following reaction: CH3OH + HCl → CH3CI + H2O The initial concentration of HCl is 2.56 M. Its concentration decreases to 1.97 M in 57.7 min. What is the rate of reaction? M/min

For the decomposition of dinitrogen pentoxide in carbon tetrachloride solution at 30 °C, the rate of the reaction is determined by measuring the appearance of O2. 2 N2O54 NO2 + O2 At the beginning of the reaction, the concentration of O2 is 0 M. After 183 min the concentration has increased to 0.380 M.What is the rate of the reaction?   (mol O2/L) /min

Consider the reaction: H2 (g) +I2 (g) → 2 HI (g) A chemist performed an experiment and monitored the concentration of I2 during the course of the reaction. The red line in the graph below represents the results obtained. Which line in the plot would best represent how the concentration of HI changes during the course of the reaction?

In the reaction 2HgO →  2 Hg + O2 the evolution of gas is used to determine the rate of reaction.  At the beginning of the reaction, 0.02 L of O2 is present.  After 15 minutes the volume of gas is 0.35 L.  What is the rate of reaction in liters/min?

A chemistry graduate student is studying the rate of this reaction: 2C1₂O5 (g) → 2Cl₂ (g) +50₂ (g) He fills a reaction vessel with C1₂05 and measures its concentration as the reaction proceeds: time (seconds) 0 0.10 [C₁₂05] 0.600M 0.215M 0.20 00. 0.131M 0.30 0.0941 M 0.40 0.0734M Use this data to answer the following questions. Write the rate law for this reaction. Calculate the value of the rate constant k. Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. rate k = - k 0 ☐x10 X Ś
