WINSTONCH [101]

First, make sure to balance your equation.

3H2(g) + N2(g) ⇄ 2NH3(g)

Now, you can write your Kc expression. Remember that Kc is products over reactants, and the exponent for each product or reactant is based on its coefficient.

Kc = [NH3]^2 / [H2]^3[N2]

A sample of helium gas has a volume of 1.25 L and a temperature of 22 °C, under a constant pressure. What is the new volume if t
Digiron [165]

Answer:

the new volume is 1.35L

Explanation:

The computation of the new volume in the case when the temperature rises to 45 degrees is shown below:

GIven that

Volume = 1.25L

And, the temperature is 22 degrees celsius

So, T_1 = (275 + 22)k

= 297 k

Now

T_2 = (275 + 45)k

= 320 k

Now as it is a constant pressure

So, the new volume is

\frac{V_1}{T_1} = \frac{V_2}{T_2}  \\\\V_2 = \frac{V_1}{T_1}\times T_2 \\\\= \frac{1.25}{297}\times 320

= 1.35L

hence, the new volume is 1.35L
