<u>Answer: </u>The correct answer is Option b.
<u>Explanation:</u>
Oxidizing agent is defined as the chemical reagent which helps the other chemical compound to get oxidized and itself gets reduced. The oxidation state for these species gets reduced because they are undergoing reduction reaction.
For the given chemical equation:
Oxidation state of Chromium is getting reduced from +6 to +3 and oxidation state of chlorine getting increased from -1 to 0.
Hence, acts like and oxidizing agent because it is itself getting reduced to
Therefore, the correct answer is Option b.
Answer : The formic acid pressure is, 99 torr
Explanation :
The given chemical reaction is:
Initial pressure a 0 0
At time 't' (a-x) x x
According to the Dalton's law,
.........(1)
As we are given that:
Initial pressure = a = 220 torr
Now put the value of 'a' in equation 1, we get:
Thus, the formic acid pressure is, 99 torr
Answer: Option (b) is the correct answer.
Explanation:
According to Le Chatelier's principle, any disturbance caused in an equilibrium reaction will tend to shift the equilibrium in a direction away from the disturbance.
For example,
Hence, expression for equilibrium constant will be as follows.
Since, the concentration for a solid substance is considered as 1 or unity. Therefore, adding or removing a solid will not affect the equilibrium.
Thus, we can conclude that according to Le Châtelier’s Principle, the amount of solid reactant or product present does not have an impact on the equilibrium because the solid does not appear in the equilibrium constant, so adding or removing solid has no effect.
