Question

Can you help me on this question I found on my practice worksheet for thermochem?

The combustion of methanol is shown by the following
2 CH₂OH()+30₂(g) → 2 CO₂(g) + 4H₂O(g)
From the given data,
(a) find the enthalpy of reaction for the equation above.

(b) state the molar enthalpy of combustion of methanol.
(c) state whether the reaction is endothermic or exothermic.
(d) What mass of water could be heated from 20.0 °C to 35.0 °C by the burning of 2.57 mol of
methanol?

Expert Solution

Step 1: Given

Given:

$2 space CH subscript 3 OH left parenthesis straight l right parenthesis space plus space 3 space straight O subscript 2 left parenthesis straight g right parenthesis space rightwards arrow space 2 space CO subscript 2 left parenthesis straight g right parenthesis space plus space 4 space straight H subscript 2 straight O left parenthesis straight g right parenthesis$

Here, we have to

determine the enthalpy of the reaction.
molar enthalpy of combustion of methanol.
predict whether the given reaction is exothermic or endothermic.
