D. The average kinetic energy increases, and the particles collide more frequently.

Explanation:

When the temperature of a gas is increased, the average kinetic energy increases and the particles collide more frequently with one another and the walls of the container.

The temperature of a gas is a measure of the average kinetic energy of the molecules.
When temperature increases, the frequency of ordinary and effective collision increases per unit time.

What is the value for ∆Soreaction for the following reaction, given the standard entropy values? 2H2S(g) + SO2(g) 3Srhombic(s) +

Mademuasel [1]

Answer: $\Delta S^{0}$ for the reaction is -186.75 J/K

Explanation:

Change in entropy ( $\Delta S^{0}$ ) for the given reaction under standard condition is given by-

$\Delta S^{0}$ = $[3\times S_{rhombic}^{0}_{(s)}]+[2\times S_{H_{2}O}^{0}_{(g)}]-[2\times S_{H_{2}S}^{0}_{(g)}]-[1\times S_{SO_{2}}^{0}_{(g)}]$

So $\Delta S^{0}$ = $[3\times 31.8 J/K.mol]+[2\times 188.825 J/K.mol]-[2\times 205.79 J/K.mol]-[1\times 248.22 J/K.mol]$ = -186.75 J/K

In a chemical reaction, the difference between the potential energy of the products of the potential energy of the reactants is

natka813 [3]

In a chemical reaction, the difference between the potential energy of the products and the potential energy of the reactants is equal to the heat of the reaction<span>. This is, the net energy released or absorbed (change) during a chemical reaction is the sum of the potential energy of the products less the sum of the potential energy of the reactants.</span>

Write the symbol for the missing reactant.

Tcecarenko [31]

There is a shortcut trick while doing such fill in the blanks of nuclear reactions of hydrogen and helium

Let a,b,care elements of set N

$\\ \rm\Rrightarrow {}^{a}_1 H+{}^b_1H={}^c_2He\dots$

Here c must be a+b+1

Now

for our question

Hence b=4-3+1=1+1=2

The missing place should b e deuterium of heavy water

In nuclear reactions energy is released so it's mentioned on product side not reactant side
