The equivalent conductance at infinite dilution of a weak acid such as HF
can be determined by extrapolation of measurements on dilute solutions of HCl, HBr and HI
can be determined by measurement on very dilute HF solutions
can best be determined from measurements on dilute solutions of NaF, NaCl and HCl
is an undefined quantity
For a reaction of type A + B products, it is observed that doubling concentration of A causes the reaction rate to be four times as great, but doubling amount of B does not affect the rate. The unit of rate constant is
s-1
s-1 mol L-1
s-1 mol-1 L
s s-1 mol-2 L-2
A chemical reaction was carried out at 320 K and 300 K. The rate constants were found to be k1 and k2 respectively. Then
k2= 4k1
k2 = 2k1
k2= 0.25 k1
k2= 0.5k1
