describe how energy flows through each level in this energy pyramid. is all the matter and energy from one level transferred to

photoshop1234 [79]

Explanation:

Energy pyramid refers to the representation of how the energy is transferred in the organism at each level in an ecosystem. The producers are kept at the lower level whereas the top carnivore at the top.

1. The energy linearly flows in the energy pyramid which can be represented in the form of the food chain. In a food chain, the energy flows when one organism eats another organism which after digestion provides energy.

2. the energy is transferred in a food chain according to ten per cent law which states that only ten per cent of energy will be transferred between the organism in a food chain.

The rate of disappearance of HBr in the gas phase reaction 2 HBr(g) → H2(g) + Br2(g) is 0.140 M s-1 at 150°C. The rate of appear

djverab [1.8K]

Answer: The rate of appearance of $Br_2$ is $0.0700Ms^{-1}$

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

$2HBr(g)\rightarrow H_2(g)+Br(g)$

The rate in terms of reactants is given as negative as the concentration of reactants is decreasing with time whereas the rate in terms of products is given as positive as the concentration of products is increasing with time.

Rate in terms of disappearance of HBr = $-\frac{1d[HBr]}{2dt}Rate in terms of appearance of [tex]H_2$ = $\frac{1d[H_2]}{dt}$
