What is the mist likely effect to the reaction is there is an increase in pressure on this reaction

B. The reaction rate decreases

Explanation:

Increasing the pressure on a reaction involving reacting gases increases the rate of reaction.  

Changing the pressure on a reaction that involves only solids or liquids has no effect on the rate.

If you increase the pressure of a gas, you squeeze it into a smaller volume

Greater density of molecules increases the number of collisions. When you decrease the pressure, molecules don't hit each other as often and the rate of reaction decreases.  

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

catya your not at all which answer i've seen you do this on another question!
