The hydrogen gas used to make ammonia can be made from small hydrocarbons such as methane in the so-called steam-reforming process, run at high temperature and pressure. a. If 3.2 atm of methane at 21 °C are introduced into a container, to what temperature must the gas be heated to increase the pressure to 12 atm

temperature is 829.5 °C

Explanation:

given data

methane = 3.2 atm

temperature = 21 °C = 21 + 273 = 294 K

increase the pressure = 12 atm

to find out

what temperature must the gas be heated

solution

we know at constant volume

pressure is directly proportional to temperature

so

we can say

P (initial) / T (initial) = P (final) / T (final) ... 1

here P is pressure and T is temperature

put the value

3.2 / 294 = 12 / T (final)

T (final) = 12 * 294 / 3.2

T (final) = 1102.5 K

so T (final) = 1102.5 - 273

T (final) is 829.5 °C
