question

(a) the rate constant for a first order reaction is . how much time will it take to reduce the initial concentration of the reactant to its value ? 

(b) write two factors that affect the rate of a chemical reaction. 

(c) write two conditions for the collisions to be effective collisions.

 

 

 

 

 

 

(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 areconcentration of reactants andtemperature

(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.
