Answer:

Original: P₁ = 710 mmHg, V₁ = 14.8 mL, T₁ = (273.2 + 11.0) K = 284.2 K

New: P₂ = 370 mmHg, V₂ = ? mL, T₂ = (273.2 + 20.0) K = 293.2 K

Combined gas law: P₁V₁/T₁ = P₂V₂/T₂

Then, V₂ = V₁ × (P₁/P₂) × (T₂/T₁)

Calculated new volume, V₂ = (14.8 mL) × (710/370) × (293.2/284.2) = 29.3 mL

In cellular chemical pathways, the product(s) of any particular reaction are often quickly consumed by the next reaction in the
mezya [45]

Answer:

Tend to keep the product concetration <u>low</u> and therefore drive the reaction <u>righward</u>

Explanation:

The fact the products of a reaction are quickly consumed by the next one would tend to keep the product concetration low and therefore drive the reaction righward (to the products).

This happens because the system will not achive equilibrium between the reactants and the product, and will keep producing it util the system achives equilibrium or the reactants dry out.
