The pressure will increase to #"5.63 atm"#.

Explanation:

Use Gay-Lussac's law, which states that when the volume of a gas is kept constant, its volume and pressure are directly proportional. The equation for this gas law is #P_1/T_1=P_2/T_2#.

#P_1="5.00 atm"#
#T_1="5.00"^"o""C"+273.15="278.15 K"#
#P_2=???#
#T_="40.0"^"o""C"+273.15="313.15 K"#

Solution
Rearrange the equation to isolate #P_2# and solve.

#P_2=(P_1T_2)/T_1#

#P_2=((5.00"atm") * (313.15"K"))/(278.15"K")="5.63 atm"#
