Question
For a certain chemical reaction variation in the concentration ln [R] vs. time plot is given alongside.

For this reaction:

  1. What is the order of the reaction?
  2. What are the units of rate constant k?
  3. Give the relationship between k and t1/2 (half-life period).
  4. What is the slope of the curve?
  5. Draw the plot log [R]0 /[R] vs time t(s).

✓

Answer

  1. First order.
  2. Time-1 (s-1)
  3. $\text{k}=\frac{0.693}{\text{t}_{1/2}}$
  4. Slope = - k (rate constant).
  5.

After watching a programme on TV about the presence of carcinogens (cancer causing agents) Potassium bromate and Potassium iodate in bread and other bakery products, Veena, a class XII student, decided to make others aware about the adverse effects of these carcinogens in foods. She consulted the school principal and requested him to instruct the canteen contractor to stop selling sandwiches, pizzas, burgers and other bakery products to the students. The principal took an immediate action and instructed the canteen contractor to replace the bakery products with some proteins and vitamins-rich food like fruits, salads, sprouts, etc. The decision was welcomed by the parents and students.
