  1. Find the rate of the following chemical process/reaction.
    i) 20 g of sodium metal took 90 seconds to react in water completely. Give the rate of this reaction in grams per minute.
    ii) Give the rate of the same reaction in grams per second.
    1. Use the rate equation and the rate of the following chemical process/reaction to find other factors.
      In one experiment, burning propane (C3H8) in oxygen produces CO2 gas at a rate of 12 liters every 15 minutes.
      1. Find the rate of this reaction in liters per hour.
      2. What volume of CO2 gas will be produced after 3 hours and 45 minutes of this experiment running?
    2. Find the rate of the following chemical process/reaction.
      The following is a neutralization reaction between an acid and a base in water:

      H2SO4+2NaOHNa2SO4+2H2O\mathrm{H_2SO_4 + 2NaOH \to Na_2SO_4 + 2 H_2O}

      1. Water is being produced at a rate of 0.85 mol per minute in this process during one experiment. What is the rate of Na2SO4 production in this process?
      2. What is the rate of NaOH consumption?
      3. What mass of water, in grams, will be produced if this reaction runs for 25 minutes?
