From the graph, predict the order of the reaction:
Zero order reaction
Solution: In a zero-order reaction, the rate is independent of the concentration of the reactants, meaning the concentration decreases in a linear manner over time. The graph for a zero-order reaction will typically show a straight line when plotting concentration vs time.
For this question, based on the provided graph's behavior, the correct answer is Option (c): Zero order reaction.
A first-order reaction has a half-life of 693 seconds. What will be its rate constant?
Arrange the following in increasing order of their osmotic pressure generation at 298 K:
(The cell wall is permeable to water and not to the solute molecules)
(A) If a cell containing 0.5 moles of solute dissolved in 1 L of water is immersed in pure water.
(B) If a cell containing 0.25 moles of solute dissolved in 1 L of water is immersed in pure water.
(C) If a cell containing 0.1 moles of solute dissolved in 0.01 L of water is immersed in pure water.
(D) If a cell containing 0.2 moles of solute dissolved in 0.05 L of water is immersed in pure water.
