Question

If temperature is held constant for an ideal gas, as P and V change for a given gas sample, the PV of products will_____. increase decrease be constant change

Answer 1

Answer:

The PV of products will be constant.

Explanation:

Ideal gas equation-   PV = nRT

where P is pressure of gas, V is volume of gas, n is number of moles of gas, R is gas constant and T is temperature (in Kelvin) of gas.

Now, number of moles of a gas remain constant with change in state variables.

So, if T is constant then the term "nRT" remins constant.

As PV is equal to nRT therefore PV will be constant if temperature is held constant.

In another way we can say if P is increased then V will decrease or vice versa.

Answer 2

Answer:

PV=nRT

Explanation:

V=RTn

P

rearrangement gives

• PV=nRT
• R=PV

nT

where P=pressure

V=volume

n=number of moles

R=ideal gas(0.0820atmdm/3 mol/k)

T=temperature in kelvin
