Answer:
The Equilibrium will shift towards the left.
Explanation:
The reaction for the formation of nitric oxide is follows,
Expression for reaction quotient is as follows,
Putting the values according to the data given and calculating reaction quotient for the reaction
So, the reaction quotient is 0.16.
and the value of K is 0.01 .
Q>K
Since the value of K is less than Q, therefore the reaction will shift towards left.
Answer : The molar heat of fusion for substance X is, 775.6 cal/mol
Explanation :
First we have to calculate the moles of substance X.
Given:
Molar mass of substance X = 58.45 g/mole
Mass of substance X = 326.0 g
Now put all the given values in the above expression, we get:
Now we have to calculate the molar heat of fusion for substance X.
where,
Q = heat releases = 4325.8 cal
= molar heat of fusion for substance X = ?
n = moles = 5.577 mol
Now put all the given values in the above expression, we get:
Thus, the molar heat of fusion for substance X is, 775.6 cal/mol
