)for a certain reaction, kc=0.514 and kf=38.2 m^-2 x s^-1 . calculate the value of the reverse rate constant, kr, given that the reverse reaction is of the same molecularity as the forward reaction.
express your answer with the appropriate units.

part b)

for a different reaction, kc=1.28×10^3 , kf=1.77×10^3 s^-1 , and kr=1.38 s^-1 . adding a catalyst increases the forward rate constant to 7.47×10^5 s^-1. what is the new value of the reverse reaction constant, k_r, after adding catalyst?
express your answer with the appropriate units.

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.

idk what is it? is this a question that you know the answer or u dont
