A+b -> c+d this reaction will most likely occur at the greatest rate if a and b represent a. solutions of nonpolar molecular compounds. b. ionic compounds in the solid phase. c. nonpolar molecular compounds in the solid phase. d. solutions of ionic compounds.

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m

The answer is sucrose.
