In a chemical reaction, the equilibrium constant refers to the value of its reaction quotient at chemical equilibrium, that is, a condition attained by a dynamic chemical system after adequate time has passed, and at which its composition has no measurable capacity to undergo any kind of further modification.

The given reaction is: HCN (aq) + OH⁻ = CN⁻ (aq) + H2O (l)

The equilibrium constant = product of concentration of products / product of concentration of reactants

(Here, H2O is not considered as its concentration is very high)

So, Keq = [CN⁻] / [HCN] [OH⁻]

"A base is a substance that produce OH-ions." Which definition of a base is this?

Andru [333]

Answer:

C. Arrhenius

An Arrhenius base is a substance that dissociates in water to form hydroxide (OH–) ions. In other words, a base increases the concentration of OH– ions in an aqueous solution.

A geometric isomer with two alkyl groups on the same side of the carbon-carbon double bond is called

grandymaker [24]

Answer:
A geometric isomer with two alkyl groups on the same side of the carbon-carbon double bond is called cis Isomer.

Explanation:
Geometric isomerism takes place about the double bond in alkenes when the alkyl groups are either situated at the same side (cis) or are situated opposite (trans) to each other.

Example:
cis-2-Butene (highlighted red)

trans-2-Butene (highlighted blue)
