The volume of a gas decreases to half of its original volume, but the gas maintains the same number of moles and temperature. according to the ideal gas law, what will most likely happen to the pressure?

Pressure will be doubled if volume of gas decreases to half of its original volume

Explanation:

Ideal gas law:

where, P is pressure, V is volume, n is number of moles, R is gas constant and T is temperature in kelvin scale.

Here n and T are constants. Also R is a constant,

Hence we can write,

where, and are initial and final pressure respectively. and are initial and final volume respectively.

Here,

So,

or,

So, pressure will be doubled if volume of gas decreases to half of its original volume

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
