Group Starts True

A rightward change in equilibrium.

The concentration of gases = [H2] will decrease, [N2] will increase, [NH3] will increase when the new equilibrium is reached.

Additional heat is produced.

The forward and backward reactions' rates quicken in the new equilibrium.

The equilibrium constant decreases as more heat is released.

Anika [276]

Answer:

5)0.53liters

6)1.634.6°c

Explanation:

using \:  charles \: law \\ v1 \div t1 = v2 \div t2

5) v1=25liters, t1=12000°c. v2=?, t2=250°c

v2=(250×25)/12000

v2=6250/12000

v2=0.52liters

6)v1=130,v2=85, t1=2500, t2=?

t2=(85×2500)/130

t2=212500/130

t2= 1634.6°c
