dx/dt is rate of change of concentration with respect to?
Correct answer: C. Time
- A. Temperature
- B. Pressure
- C. Time
- D. None of these
Explanation
Option A: The rate of change of concentration with respect to temperature would be represented as dC/dT, where dC is the change in concentration and dT is the change in temperature. This option is not applicable in the given question since the rate of change of concentration is specifically being considered with respect to time. Option B: Similarly, the rate of change of concentration with respect to pressure would be represented as dC/dP, where dC is the change in concentration and dP is the change in pressure. However, this option is also not applicable in the given question as the rate of change of concentration is being considered with respect to time, not pressure. Option C: The rate of change of concentration with respect to time is represented as dx/dt, where dx is the change in concentration and dt is the change in time. It measures how the concentration of a substance changes over time. Option D: This option implies that none of the provided options (temperature, pressure, or time) is correct for representing the rate of change of concentration. However, in this case, the correct answer is option C, as explained above.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
