Area bounded between the parabola \(y=x^2-2\) and the line \(y=x\) in square units is:
- A \(\frac{9}{2}\)
- B \(\frac{11}{2}\)
- C \(\frac{7}{2}\)
- D 5
Answer & Solution
Correct Answer
(A) \(\frac{9}{2}\)
Step-by-step Solution
Detailed explanation
\(x^2-x-2 = 0 \Rightarrow x=-1, 2\) \(A = \int_{-1}^{2} (x - (x^2-2)) dx = \int_{-1}^{2} (-x^2+x+2) dx\) \(A = \left[ -\frac{x^3}{3} + \frac{x^2}{2} + 2x \right]_{-1}^{2}\) \(A = \left( -\frac{8}{3} + 2 + 4 \right) - \left( \frac{1}{3} + \frac{1}{2} - 2 \right)\)…

The concentration dependence of the rate of a reaction is called the differential rate equation. It is not always convenient to determine the instantaneous rate, as it is measured by calculating the slope of the tangent at point 't' in the concentration vs time plot. This makes it difficult to determine the rate and hence the order of the reaction. This difficulty is overcome by integrating the differential rate equation. This integrated rate equation gives a direct relation between concentrations at different times and the rate constant. The integrated rate equations are different for the reactions having different reaction orders.

Electrochemistry is the study involving two types of processes. One type involves the production of electricity from the energy released during a spontaneous chemical reaction. Galvanic cells like Daniel cells are used to produce electricity from the redox reaction. Nernst equation of a galvanic cell gives the relation between the standard cell potential and the concentration of the species involved in the redox reaction. The second type of study involves the cells in which electrical energy is used to bring about the chemical reactions in a non-spontaneous process. The conductance of electrolytic solution depends on many factors including the nature of the electrolyte and the dimensions of the electrolytic cell.
