Answer : The concentration of SO₂Cl₂ after 720 min will be, 
Explanation :
Expression for rate law for first order kinetics is given by:
where,
k = rate constant = 
t = time passed by the sample = 720 min
a = initial amount of the reactant = 
a - x = amount left after decay process = ?
Now put all the given values in above equation, we get
Therefore, the concentration of SO₂Cl₂ after 720 min will be,
From the statement of Hess' law, the enthalpy of the reaction A---> C is +90 kJ
<h3>What is Hess' law?</h3>
Hess' law of constant heat summation states that for a multistep reaction, the standard enthalpy of reaction is always constant and is independent of the pathway or intermediate routes taken.
From Hess' law, the enthalpy change for the reaction A ----> C is calculated as follows:
A---> C = A ---> B + B ---> C
ΔH of A---> C = 30 kJ + 60 kJ
ΔH = 90 kJ
Therefore, the enthalpy of the reaction A---> C is +90 kJ
The above reaction A---> C can be shown in the enthalpy diagram below:
A -------------------> C (ΔH = +90 kJ)

\ / (ΔH = +60 kJ)
(ΔH = +30 J) \ /
> B
