Select the correct answer from each drop-down menu. in a reversible reaction, the forward reaction takes place the reverse reaction. such a reaction, on reaching equilibrium, will have .

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

the correct answer would be b) volume versus temperature, because they are also directly proportional.
