Answer:
110.7 kpa or 1.097 atm your choice of pressure units
Explanation:
We can assume the Volume is constant since we are not told other wise and it is indeed a car. We can Use P1/T1= P2/T2
So (T2xP1 )/ T1 = P2
(318Kx101.3kpa)/291k = 110.7 kpa or 1.097 atm your choice of pressure units
if your wondering why i used Kelvin gas laws are always in units of Kelvin

NH₄Cl (s) ⇔ NH₃ (g) + HCl (g)
Δn = 2 (gas only)
R = 0.082
T = 427 + 273 = 700 K
4.8 = Kc (0.082 x 700)²
Kc = 1.45 x 10⁻³
The answer is d. lead and sulfuric acid
