As I would understand these terms, emotive language is the use of language when expressing emotions or emotive elements of language of ordinary communication. Emotional appeals are form of specifically emotive communication, verbal, gestural or bodily.

Yes. That is why letters appealing for monetary donations come with visuals of handicapped person struggling or outperforming normal people. It goes to show that emotive words are not enough all the more so when the target audience does not read.

I remember the anti-dengue poster are always filled with visuals showing the threats of the disease caused by the Aedes mosquitoes.  The red and black colors designed to generate fear through the picture of a mosquito sucking blood is good enough an emotional appeal.

 Dear Mr. Sew,

An emotional appeal --- is used to sway the emotions of an audience to make them support the speaker's argument.

Emotional appeal can be accomplished in a multitude of ways:

--By a metaphor or storytelling, common as a hook

--By a general passion in the delivery

--By an overall emotion

--By the sympathies of the speech or writing as determined by the audience

The pathos of a speech or writing is only ultimately determined by the audience.

Writers use emotive language in order to have a greater emotional impact on their audience. Such wording is also known as high-inference language or language persuasive techniques.

Emotive Language --- Speakers and writers wanting to persuade us to agree with them often try to engage our emotions. They can do this by including words that carry emotional weight. 

This can be persuasive because it encourages the reader to respond on an emotional level, rather than considering the facts, or it may subtly affect the way the reader views the topic.

Dear Cameen

I think

Emotional appeal=emotive language+non-verbal communication

Emotive language and emotional appeal have the same goal: to appeal to emotion (the extra-rational) for specific effects and goals. The difference is that the first, emotive language, is restricted to words. The technique works only if the sender and the receiver share the worldview where those emotions are linguistically located. Thus, 'dulce est decorum est pro patria mori' in Ancient Rome could be an emotive slogan evoking patriotism but after World War 1 it was ironical. In religious societies the use of words appealing to the sacred evokes emotion. But words by themselves are not enough. To have emotive appeal there are other conditions also. First, the emotion should be shared. Secondly, the person or persons appealing to emotions-- through words, tone, pauses, body language, facial expression, tears,  images, sounds etc-- should be perceived to be sincere and not faking emotion or being hypocritical. Thirdly, the occasion should be serious not comic, farcical or false. By false I mean, if it is the rehearsal of a play or the dialogue of a film then the actors take the dialogue, no matter how much emotion is invested in it, as false since they are constantly rehearsing it and laughing at their mistakes. For the audience, even when they know it is a drama, it will appeal to emotions if executed properly. Laughter at times is the great antidote to high emotion generated through both words and other auxiliaries. However, the best orators know how to whip up hysteria by using both emotive language and appealing to their audiences' deepest emotions through their gestures, tone, silences, pauses, and body language.

Yes it is different ,Emotive language is the deliberate choice of words to elicit emotion (usually to influence). An emotional appeal is used to sway the emotions of an audience to make them support the speaker's argument. effective users of emotive language know their audiences well and are able to tailor their words to obtain the desired emotional response. An emotional appeal uses emotions as the basis of an argument's position without factual evidence that logically supports the major ideas endorsed by the presenter.
