A different rigid 5.00L cylinder contains 0.176mol of NO(g) at 298 k. A 0.176mol sample of 02(g) is added to the cylinder, where a reaction occurs to produce NO2(g)

(d) write the balanced equation for the reaction.
(e) calculate the total pressure, in atm, in the cylinder at 298k after the reation is complete

Write the balanced equation.

Before the reaction, determine the pressure from the sum of the partial pressures

partial pressure= nRT/V of each gas, then sum them.

You will have to then see what happens to the gasses: Did the ratio of the volumes change in the reaction. And, was all the reactants used up?
