Heat applied to reactant causes a faster chemical reaction. Heat is considered as ACTIVATION ENERGY.

Activation energy is the minimum amount of energy which reactants must possess in order to undergo a chemical reaction. When heat is applied to a particular set of reactants, the heat increases the kinetic energy of the reacting particles, thus enabling them to move around more rapidly. This increases the rate of collision among the reacting particles and empower the reacting particles to overcome the energy barriers and to form the products.

Answer : The conditional formation constant is $1.83\times 10^9$

Explanation :

First we have to calculate the formation constant.

As we are given that:

$\log k_f=10.65$

$k_f=10^(10.65)$

$k_f=4.47\times 10^{10}$

Thus, the formation constant is $4.47\times 10^{10}$

Now we have to calculate the conditional formation constant.

The expression used as:

$k'_f=\alpha_y^+\times k_f$

where,

$k'_f$ = conditional formation constant = ?

$\alpha_y^+$ = activity coefficient at pH 9.00 = 0.041

$k_f$ = formation constant = $4.47\times 10^{10}$

Now put all the given values in the above expression, we get:

$k'_f=(0.041)\times (4.47\times 10^{10})$

$k'_f=1.83\times 10^9$

Therefore, the conditional formation constant is $1.83\times 10^9$
