D-no effect on the rate

The answer is the first option just took the test

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other

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
