Suppose the following exothermic reaction is allowed to reach equilibrium. a(g) + 3b(g) ⇋ 2c(g) + 3d(g)then we make each of the following changes and allow the reaction to reestablish equilibrium. tell whether the amount of b present at the new equilibrium will be (i) greater than, (ii) less than, or (iii) the same as the amount of b before the change was imposed.(a) the temperature is decreased while the volume is kept constant; (b) more a is added(c) more c is added(d) a small amount of d is removed; (e) the pressure is increased by decreasing the volume

(a) The temperature is decreased while the volume is kept constant;

Because the reaction is exothermic when we decrease the temperature the equilibrium will shift to the right.

The amount of B will be (ii) less than before the change was imposed.

(b) more A is added

Equilibrium is shifted to the right.

The amount of B will be (ii) less than before the change was imposed.

(c) more C is added

Equilibrium is shifted to the left.

The amount of B will be (i) greater than before the change was imposed.

(d) a small amount of D is removed

Equilibrium is shifted to the right.

The amount of B will be (ii) less than before the change was imposed.

(e) the pressure is increased by decreasing the volume

The equilibrium will shift to the part where we have a lower number of moles which is the left side.

The amount of B will be (i) greater than before the change was imposed.

the answer is alpha particles hope i you

the product of the pressure and volume is also constant
