An irreversible reaction is one that:

bazaltina [42]

Answer:

(d) has an extremely large equilibrium constant.

Explanation:

Hello,

Considering a generic chemical reaction:

$aA+bB cC+dD$

The equilibrium constant is defined as:

$K=\frac{[C]^c_{eq}[D]^d_{eq}}{[A]^a_{eq}[B]^b_{eq}} \\$

Now, an irreversible chemical reaction is a reaction in which the reagents are converted into products with no chance of coming back, so, considering the previous chemical reaction, the concentration of both A and B tends to be zero, so an extremely large equilibrium constant is gotten.

Best regards.

Calculate the hydroxide ion concentration in an aqueous solution with a poh of 9.85 at 25°c.

LenaWriter [7]

The hydrogen ion concentration is calculated as follows

Ph + POh =14
ph= 14-9.85= 4.15

anti -H+
