m=2/(0+2)

m=2/2

m=1 ==> Gradient of graph

x-int: (-2, 0)

y-int: (0, 2)

Explanation:

m=(y2-y1)/(x2-x1)

m=(2-0)/(0-(-2))

m=2/(0+2)

m=2/2

m=1 ==> Gradient of graph

x-int: (-2, 0) ==> When y=0

y-int: (0, 2) ==> When x=0

How is enthalpy used to predict whether a reaction is endothermic or exothermic?

Radda [10]

Answer:

$329.48 KJ/mol$ heat is released by the combustion of $2 mol$ of methane

Explanation:

The value of enthalpy determines whether the reaction is exothermic or endothermic. If the enthalpy change is positive, then the reaction is endothermic (heat or energy released) and if the enthalpy change is negative then the reaction is exothermic (heat or energy absorbed).

$2CH_4(g)+4O_2(g) => 2CO_2(g)+4H_2O(g)$
