Question

3. Food deteriorates more slowly in a refrigerator because (10.1) 

A. more reactants are added 

B. products are removed 

C. the energy of activation is higher 

D. fewer collisions have the energy of activation 

E. collisions have the wrong orientation upon impact 

4. A reaction reaches equilibrium when (10.2) 

A. the rate of the forward reaction is faster than the rate of the reverse reaction 

B. the rate of the reverse reaction is faster than the rate of the forward reaction 

C. the concentrations of reactants and products are changing 

D. fewer collisions have the energy of activation 

E. the rate of the forward reaction is equal to the rate of the reverse reaction

Answer 1

3. In refrigerator, temperature is less. Thus, atoms has less energy due to collisions are less and fewer collisions have the energy of activation.

option D.

4. At equilibrium ,Reaction is in dynamic , but

Rate of forward reaction = Rate of backward reaction

option E
