Question

Answer the following questions based on the reaction below. Report all answers to three significant figures.

AgNO3(aq) + NH4Cl(aq) AgCl(s) + NH4NO3(aq)

The concentration of AgNO3 is 0.386 M at the start of the reaction, and 0.104 M after 133 seconds. The initial concentrations of the products are zero.

1. What is the average rate of reaction (in M/min) over this time period?

2. What is the average rate of change (in M/min) of AgNO3 in the first 133 seconds. Submit Answer

3. What is the average rate of change (in M/min) of NH4NO3 in the first 133 seconds. Submit Answer

4. What is the concentration (in M) of NH4NO3 after 133 seconds.

Explanation / Answer

1. Average Rate of reaction = - (change in concentration of reactant)/(change in time) = -(0.104-0.386)/(133/60) = 0.127 M/min

2. Average Rate of change of AgNO3 = (0.104-0.386)/(133/60) = -0.127 M/min

4. Concentration of NH4NO3 = 0.386-0.104 = 0.282 M

3. Average Rate of change of NH4NO3 = (0.282-0)/(133/60) = 0.127 M/min
