Measuring and calculating rate of reaction

The sealed vessel was left for the reaction to proceed. Suggest two properties of the system, other than its colour, that could be measured to follow the progress of the reaction over time, and predict how each would change as the forward reaction proceeds.

(i) Determine, using a suitable construction drawn on the graph, the initial rate at which $\ce{CO2(g)}$ is released, in $\mathrm{g\,s^{-1}}$, in the reaction with 1.20 $\mathrm{mol\,dm^{-3}}$ $\ce{HNO3(aq)}$. (ii) Determine the average rate of release of…

Which are units for rate of reaction? A. $\mathrm{s\,mol^{-1}\,dm^{3}}$ B. $\mathrm{mol\,dm^{-3}\,min}$ C. $\mathrm{mol\,dm^{-3}\,min^{-1}}$ D. $\mathrm{mol\,min^{-1}}$

Which of the following could be used to follow the progress of the reaction between calcium carbonate and dilute nitric acid? $\ce{CaCO3(s) + 2HNO3(aq) -> Ca(NO3)2(aq) + H2O(l) + CO2(g)}$ I. A balance recording the mass of the open flask and its contents II. A…

In a kinetics experiment, excess dilute hydrochloric acid was added to a fixed mass of marble chips (calcium carbonate), and the volume of carbon dioxide gas produced was measured over time. What is the average rate of gas production for the first 20 seconds?…

The student's results are shown in the graph. (i) Calculate the average rate at which the iron(II) concentration fell in the 24 h flask during the 21 days. Include units. (ii) Before starting, the student proposed the hypothesis: "The longer a solution is left…
