If a graph is plotted with concentration data of a reactant in a chemical reaction the curve is_.
Correct answer: B. Falling
- A. Rising
- B. Falling
- C. U shaped
- D. None of these
Explanation
The concentration of reactant decreases with respect to time so the curve in the concentration-time graph should be "falling".

About Rate of Reaction
Reaction rate measures the change in concentration of a reactant or product per unit time. Questions connect rate with concentration, temperature, pressure, surface area, catalysts and nature of reactants, and may involve rate laws, reaction order, activation energy and collision theory. Rate describes speed, whereas equilibrium describes the final balance of opposing reactions.
