Answer to Question #67819 in Physical Chemistry for rahina

Question

Question 4 : Equilibrium is a state of dynamic molecular behaviour, meaning that
reactants turn into products and products turn into reactants at different rates.
reactants turn into products and products turn into reactants at equal rates
products continually turn into reactants at a progressively faster rate.
the reaction eventually comes to a stop.

Question 5 : Milk sours more rapidly in summer than in winter because
in summer, the temperature Is high due to which effective collisions increase and hence the rate of reaction becomes fast
none of the above
in summer, the energy of activation decreases and hence the of reaction becomes fast
in winter, number of molecules per unit volume increases and hence the rate of reaction becomes fast

Answer 1

Question 4: reactants turn into products and products turn into reactants at equal rates
Question 5: in summer, the temperature is high due to which effective collisions increase and hence the rate of reaction becomes fast
