Concentration (M)
0.0784 moles of substance A is dissolved in water to make a 2.00 L solution. Then, substance B is added, without changing the
volume of the solution, and the following reaction takes place:
2A (aq) + 3B (aq) →2C (aq)
During the course of the reaction, concentration of A is monitored. After 100 seconds into the reaction, it was found that 0.0570
moles of A is remaining.
Calculate the rate of disappearance of A in the first 100 seconds of the reaction.
Hint: Since rate is defined as the change in molar concentration (mol/L) over time, start by calculating molarity of A in the
beginning of the reaction, and 100 seconds after.

- Substances that poison a catalyst pose a major concern for many engineering designs, including those for catalytic converters. One design option is to add materials that react with potential poisons before they reach the catalyst. Among the commonly encountered catalyst poisons are silicon and phosphorus, which typically form phosphate or silicate ions in the oxidizing environment of an engine. Group 2 elements are added to the catalyst to react with these contaminants before they reach the working portion of the catalytic converter. If estimates show that a catalytic converter will be exposed to 625 g of silicon during its lifetime, what mass of beryllium would need to be included in the design?arrow_forwardIodomethane (CH3I) is a commonly used reagent in organic chemistry. When used properly, this reagent allows chemists to introduce methyl groups in many different useful applications. The chemical does pose a risk as a carcinogen, possibly owing to iodomethanes ability to react with portions of the DNA strand (if they were to come in contact). Consider the following hypothetical initial rates data: [DNA]0 ( mol/L) [CH3I]0 ( mol/L) Initial Rate (mol/Ls) 0.100 0.100 3.20 104 0.100 0.200 6.40 104 0.200 0.200 1.28 103 Which of the following could be a possible mechanism to explain the initial rate data?

- Candle wax is a mixture of hydrocarbons. In the reaction of oxygen with candle w ax in Figure 11.2, the rate of consumption of oxygen decreased with time after the flask was covered, and eventually' the flame went out. From the perspective of the kinetic-molecular theory, describe what is happening in the flask. FIGURE 11.2 When a candle burns in a closed container, the flame will diminish and eventually go out. As the amount of oxygen present decreases, the rate of combustion will also decrease. Eventually, the rate of combustion is no longer sufficient to sustain the flame even though there is still some oxygen present in the vessel.arrow_forward11.17 Ammonia can react with oxygen to produce nitric oxide and water: 4NH3(g)+5O2(g)4NO(g)+6H2O(g) If the rate at which ammonia is consumed in a laboratory experiment is 4.23 ×10-4 mol L_1s_l, at what rate is oxygen consumed?
