Answer:
Explanation:
a )
From the graph given , energy of reactant = 0
b )
energy of product = -15 kJ
c )
ΔH = energy of product - energy of reactant
= -15 - 0 = - 15 kJ
ΔH is negative so reaction is exothermic .
d ) Activation energy = 25 - 0 = 25 kJ .
e ) Energy released = 15 kJ .
3024.75 Joules needed to warm iron
In the reaction 2co ( g) + o2( g) → 2co2( g), the ratio of moles of oxygen used to moles of co2produced is 1:2.
Inertia depends on the mass of an object.
