Answer:

Explanation:
k stand for equilibrium constants in terms of reaction
The higher the value of an equilibrium constant the faster the equilibrium reaction comes to completion.
Consider the example below:
⇄
where

For a faster reaction the numerator i.e. the right hand side of the equation have to be higher than the left hand side (the denominator). therefore the higher the numerator, the higher the value of the equilibrium constant and the faster the reaction get to completion thus option c is correct.
Has markings along the cylinder/beaker that indicate the volume of liquid inside them. .
Answer:
Explanation:
Look at the reaction.
2NH3 ===> N2 + 3H2
It's a molecule that is breaking down to two elements on the periodic table. We used to call such a thing as a simple decomposition.
it has less tightly bound electrons, is able to lose electron easily as compare to metal B at it has 4 unpaired electron in 3d sub-shell.
