The rate of a chemical reaction will be affected more by which? entropy enthalpy both enthalpy and entropy neither enthalpy nor entropy

Enthalpy => Heat Effects => changes in temperature

Explanation:

Rate of Rxn is affected by changes in 5 issues ...

C => Concentration

A => Surface Area

N => Nature (Chemical Structure)

T => Temperature (Enthalpy = Heat of Rxn)

C => Catalyst

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
