Answer:

-6300J

Explanation:

The quantity of heat required to raise the temperature of a substance per unit of mass could be written as:

Q = -m×C×ΔT

Where Q is heat, m is mass of substance, C is specific capacity and ΔT is change in temperature.

Replacing:

Q = -175g × 2.4J/gK × (38.6°C-23.7°C)

Q = -6258J ≡ -6300J

Answer: 0.151

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

$2HBr(g)\rightarrow H_2(g)+Br_2(g$

The rate in terms of reactants is given as negative as the concentration of reactants is decreasing with time whereas the rate in terms of products is given as positive as the concentration of products is increasing with time.

$Rate=-\frac{1d[HBr]}{2dt}=+\frac{1d[H_2]}{2dt}=+\frac{1d[Br_2]}{dt}$
