A 36.2 g object has a heat capacity of 12.5 J/ oC. How much energy (in J) is required to raise the temperature by 5.73 oC?

iren2701 [21]

Answer:

$\Delta H=2592.825\ J$

Explanation:

The expression for the calculation of the enthalpy change of a process is shown below as:-

$\Delta H=m\times C\times \Delta T$

Where,

$\Delta H$ is the enthalpy change

m is the mass

C is the specific heat capacity

$\Delta T$ is the temperature change

Thus, given that:-

Mass of object = 36.2 g

Specific heat = 12.5 J/g°C

$\Delta T=5.73\ ^0C$

So,

$\Delta H=36.2\times 12.5\times 5.73\ J=2592.825\ J$

$\Delta H=2592.825\ J$

Answer:

1. Dynamic equilibrium is a equilibrium in which the rate of forward direction is equal to the rate of backward direction. It is represented by a right left arrow.

2) Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as $K_c$

For the given chemical reaction:

$Fe^{3+}(aq)+SCN^-(aq)\rightleftharpoons [Fe(SCN)]^{2-}(aq)$

The expression for $K_c$ is written as:

$K_c=\frac{[[Fe(SCN)]^{2-}]}{[Fe^{3+}][SCN^-]}$

3) The value of $K_c$ is 1000 , which means the products are more favoured as compared to reactants and that the equilibrium lies more towards product side.
