<u>Answer:</u> The value of K_p for the equation is 2.5\times 10^3

<u>Explanation:</u>

The given chemical reaction is:

2HCN(g)\rightleftharpoons H_2(g)+C_2N_2(g);K_1

The chemical equation for which the equilibrium constant is to be calculated follows:

H_2(g)+C_2N_2(g)\rightleftharpoons 2HCN(g);K_p

As, the equation is the result of the reverse of given reaction. So, the equilibrium constant for the equation will be the inverse of equilibrium constant for the given reaction.

The value of equilibrium constant for the equation is:

K_p=\frac{1}{K_1}

We are given:

K_1=4.00\times 10^{-4}

Putting values in above equation, we get:

K_p=\frac{1}{4.00\times 10^{-4}}=2.5\times 10^3

Hence, the value of K_p for the equation is 2.5\times 10^3

A wooden artifact from a Chinese temple has a 14C activity of 42.8 counts per minute as compared with an activity of 58.2 counts
Arlecino [84]

Answer : The age of the artifact is, 2.54\times 10^3\text{ years}

Explanation :

Half-life = 5715 years

First we have to calculate the rate constant, we use the formula :

k=\frac{0.693}{5715\text{ years}}

k=1.21\times 10^{-4}\text{ years}^{-1}

Now we have to calculate the time taken to decay.

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant

t = time taken by sample = ?

a = initial activity of the reactant  = 58.2 counts per minute

a - x = activity left after decay process  = 42.8 counts per minute

Now put all the given values in above equation, we get

t=\frac{2.303}{1.21\times 10^{-4}}\log\frac{58.2}{42.8}

t=2540.5\text{ years}=2.54\times 10^3\text{ years}

Therefore, the age of the artifact is, 2.54\times 10^3\text{ years}
