    its takes 26.7 seconds for 51.3 g NaCl to dissolve in 1 L of water. What is the rate of dissolution

    describe the rate constant if the reaction was in first-order in NaCl

    how would you make NaCl dissolve faster without increasing the temperature?

    I think rate of dissolution is M/s.Can you find the molarity?

    wouldn't I just convert 51.3 g to moles

    And divide by volume in L

    to find the rate constant would it be my answer =k times the molarity

    Yep, that would be the equation. :-)

    last question how would you make NaCl dissolve faster without increasing the temperature?

    can you change the pressure or volume to increase it

    Hm, no, I don't think so. Changing the pressure doesn't really affect liquids and solids. And changing the volume would also change the concentration.
