If equal masses of each substance absorb the same amount of heat, which substance undergoes the greatest temperature change
Minchanka [31]

Answer:

See explanation

Explanation:

The heat capacity of a substance is determined by the chemical composition of the substance and its mass.

Now, if substances have equal masses, the substance with the lesser heat capacity undergoes the greater temperature change.

Hence, among the substances, the particular one with the lowest heat capacity is expected to undergo the greatest temperature change.

What is the rate constant of a first-order reaction that takes 143 seconds for the reactant concentration to drop to half of its
algol [13]

Answer:

k = 4.85 x 10⁻³ / s

Explanation:

For a first order reaction we have two very important equations we need to memorize:

ln ( N/N₀ ) = -kt

and,

0.693/ k = t₁/₂

where k is the rate constant and t i is the halflife which can be derived from the first equation.

0.693/ k = t₁/₂   ⇒  k = 0.693 / t₁/₂  

k = 0.693 / 143 s = 4.85 x 10⁻³ / s
