Bloodstain Pattern Analysis (BPA), one of several specialties in the field of forensic science, involves the study and analysis of bloodstains at a known or suspected violent crime scene with the goal of helping investigators draw conclusions about the nature, timing and other details of the crime.

The use of bloodstains as evidence is not new; however, new experts have claimed to be able to use fluid dynamics, physics, and other calculations to determine with accuracy previous events at a crime scene. For example, the shape of blood droplets might be used to draw conclusions as to how far away the victim was from a gun when they were shot.

This technique of forensic science has drawn more skeptical scrutiny since 2000; large amounts of the body of work in BPA is done by crime investigators using subjective hunches rather than scientists from other disciplines. A report released by The National Academy of Sciences in 2009 highlighted several incidents of blood spatter analysts to overstate their qualifications as well as questioned the reliability of their methods in the courtroom.

The position of equilibrium would not be appreciably affected by changes in the volume of the container for

8090 [49]

Answer:

The position of equilibrium would not be appreciably affected by changes in the volume of the container for NiO(s) + CO(g) ⇌ Ni(s) + CO2(g).

Correct Answer : Option A

Explanation:

The equilibrium position tends to change with increase or decrease in pressure or volume, or both of them. This happens because considering change in volume, when the volume of the container increases, the reactant molecule increases i.e. mole of gases and thus the position of equilibrium shifts towards the right side. Similarly in case of decreasing volume, reactant molecule decreases and the equilibrium position shifts left side.

And in case, when the mole of gases on both the sides of the equation i.e. reactant side and product side are equal, it will not have any effect on the equilibrium position on increasing or decreasing volume, or pressure.
