For the energy diagram of the chemical reaction depicted here, which of the following is the best conclusion?

the reaction is endothermic

the reaction is exothermic

the activation energy is never achieved if products form

the activation energy is the lowest energy level

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

a is the answer to this question

explanation:

thats how its supposed to be
