(a) t = (2.303/k) log [A0]/[A] = (2.303/ 60) log 1/(1/16) = 0.046 s

(b) Two factors that affect the rate of a chemical reaction are Concentration of reactants and Temperature

(c) Two conditions for the collisions to be effective collisions are Proper orientation and energy of colliding particles should be equal to or greater than threshold energy.
